-# CryptoExchange.Net Conventions
+# CryptoExchange.Net conventions
 
-This codebase uses **CryptoExchange.Net** abstractions for multi-exchange access. Each exchange has its own library (Binance.Net, Bybit.Net, OKX.Net, ...). Use `CryptoExchange.Net.SharedApis` for code that should work across exchanges.
+CryptoExchange.Net is the base dependency for exchange-specific libraries. Install Binance.Net, Bybit.Net, JK.OKX.Net, or another exchange library; use `CryptoClients.Net` when the application needs the bundle.
 
-## Multi-exchange pattern
+## Use Shared API V2
+
+For new cross-exchange code, use the fine-grained interfaces in `CryptoExchange.Net.SharedApis` and each API surface's `.SharedApi` property:
 
 ```csharp
-using Binance.Net.Clients;
-using OKX.Net.Clients;
 using CryptoExchange.Net.SharedApis;
 
-ISpotTickerRestClient binance = new BinanceRestClient().SpotApi.SharedClient;
+IGetTickerRest binance = new BinanceRestClient().SpotApi.SharedApi;
-ISpotTickerRestClient okx     = new OKXRestClient().UnifiedApi.SharedClient;
+IGetTickerRest okx = new OKXRestClient().UnifiedApi.SharedApi;
 
 var symbol = new SharedSymbol(TradingMode.Spot, "BTC", "USDT");
-
+var result = await binance.GetTickerAsync(new GetTickerRequest(symbol));
-var ticker = await binance.GetSpotTickerAsync(new GetTickerRequest(symbol));
-// ticker.Data.LastPrice — same model regardless of exchange
 ```
 
-## Symbol normalization
+Use one capability per operation, such as `IGetTickerRest`, `IGetOrderBookRest`, `IPlaceSpotOrderRest`, or `ISubscribeTradesSocket`. Do not use a broad V1 interface for new code. `.SharedClient` remains only for incremental V1 migration.
 
-`SharedSymbol(TradingMode.Spot, "BTC", "USDT")` is portable. Each library translates to its native format internally. Don't pass raw strings like `"BTCUSDT"` to shared methods.
+## Capability discovery
 
-## Symbol metadata and catalogs
+When the exchange and API surface are known, assign the typed `.SharedApi` to the required capability. When selection is dynamic, use an exchange-wide `I[Exchange]SharedApiClient` and a strongly typed reference:
-
-In 12.2.0, `SharedSpotSymbol` and `SharedFuturesSymbol` include `DisplayName` and base/quote asset classification through `SharedAssetType` (`Crypto`, `Fiat`, `TradFi`) and `SharedAssetSubType` (`StableCoin`, `Equity`, `Commodity`). Pass the matching base/quote filters to `GetSymbolsRequest` when discovery should return only a class of markets.
-
-After calling `GetSpotSymbolsAsync`, `ISpotSymbolRestClient.SpotSymbolCatalog` maps asset and symbol names to shared metadata. `IFuturesSymbolRestClient.FuturesSymbolCatalog` works the same way after `GetFuturesSymbolsAsync`. Treat either property as unavailable before its corresponding request has populated the cache.
-
-When implementing an exchange library, use `LibraryHelpers.IsStableCoin`, `IsCommodity`, and `IsEquity` only as best-effort classifiers and supply exchange-specific additions where needed.
-
-## Shared market-data quantities
-
-In 12.4.0, use `SharedOrderQuantity`-valued `Volumes` on shared spot/futures tickers and klines, and `Quantities` on shared trades. The scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete.
-
-## WebSocket order commands
-
-In 12.5.0, `ISpotOrderManagementSocketClient` and `IFuturesOrderManagementSocketClient` optionally provide place/cancel order commands over WebSocket. Their methods return `QueryResult<SharedId>`, not `WebSocketResult<UpdateSubscription>`. Check whether the exchange implements the interface.
-
-## Result pattern
-
-REST methods return `HttpResult<T>` and websocket subscription methods return `WebSocketResult<UpdateSubscription>`. Always check `.Success`. `.Exchange` property identifies which exchange responded — useful for logging.
-
-## Available shared interfaces
-
-- REST tickers/symbols/orderbook/klines/trades, orders (spot/futures, regular/trigger/TP-SL), balances, positions, fees, deposits/withdrawals, transfers
-- WebSocket tickers, book tickers, order book, trades, klines, user data, and optional spot/futures order management
-
-Each exchange documents which it implements. Not every exchange supports every operation.
-
-## Multi-exchange aggregation
-
-Run requests across exchanges concurrently via `Task.WhenAll` — the library is async-safe and concurrent requests are the norm.
 
 ```csharp
-var clients = new ISpotTickerRestClient[] { binance, okx, bybit };
+var match = sharedClient.GetCapability(
-var tasks   = clients.Select(c => c.GetSpotTickerAsync(new GetTickerRequest(symbol)));
+    SharedCapabilities.Orders.Futures.PlaceOrder.Rest,
+    TradingMode.PerpetualLinear);
+
+if (match is not null)
+    await match.Capability.PlaceFuturesOrderAsync(request);
+```
+
+`GetCapability` returns one preferred match or `null`; `GetCapabilities` returns all matches. Specify `TradingMode` when multiple API surfaces may implement the same capability. A `SharedCapabilities` reference is a lookup key, not proof of exchange support.
+
+## Symbols and parameters
+
+Use `SharedSymbol` instead of native strings such as `BTCUSDT`. The exchange library performs formatting.
+
+Capability presence does not imply support for every request property. For dynamic code, inspect `match.Options.RequestParameterRules`, `ExchangeParameterRules`, and `SupportedTradingModes`. Supply exchange-specific values through the request's `ExchangeParameters`.
+
+## Transports and results
+
+- Transport-agnostic capabilities return `IExchangeCallResult<T>`.
+- `...Rest` capabilities return `HttpResult<T>`.
+- socket command capabilities return `QueryResult<T>`.
+- `ISubscribe...Socket` capabilities return `WebSocketResult<UpdateSubscription>`.
+
+Use `.Rest` or `.Socket` on capability references when the transport matters. Otherwise exchange-wide lookup honors `PreferredTransport`, normally REST. Always check `.Success` before `.Data` and include `.Exchange` in multi-exchange logs.
+
+## Concurrent aggregation
+
+```csharp
+var clients = new IGetTickerRest[] { binance, okx, bybit };
+var tasks = clients.Select(x =>
+    x.GetTickerAsync(new GetTickerRequest(symbol)));
 var results = await Task.WhenAll(tasks);
 ```
 
+Reuse clients through dependency injection and run independent exchange calls concurrently.
+
+## V2 semantics
+
+- `GetTickerAsync` and `GetAllTickersAsync` return `SharedTicker` for spot and futures.
+- WebSocket order updates use `SharedSpotOrderUpdate` and `SharedFuturesOrderUpdate`.
+- `ICloseFullPosition` closes the entire position; use an order capability for partial closes.
+- Each exchange supports a subset of capabilities and parameter combinations.
+
 ## Hard rules
 
-- ❌ Never install `CryptoExchange.Net` alone and expect to call exchanges — it's a base library; you need exchange-specific packages
+- Never install CryptoExchange.Net alone and expect exchange endpoints.
-- ❌ Never mix exchange-specific models in cross-exchange code (use `SharedSymbol`, `SharedSpotTicker`, etc.)
+- Never pass exchange-native models or symbols through shared services.
-- ❌ Never use `.Result` / `.Wait()` — async-only
+- Never assume a capability or request field is supported; resolve and inspect it.
-- ❌ Never iterate sequentially when concurrency is fine — `Task.WhenAll` is your friend
+- Never use `.Result` or `.Wait()`.
-- ❌ Never instantiate clients per-request — reuse via DI
+- Never instantiate exchange clients per request.
-- ✅ Always use `.SharedClient` for cross-exchange code
+- Prefer `Task.WhenAll` for independent cross-exchange calls.
-- ✅ Always check `.Success` before reading `.Data`
+- Prefer `.SharedApi` and fine-grained V2 interfaces for new code.
-- ✅ Always log with `.Exchange` so multi-exchange logs are decipherable
-- ✅ Always handle "not supported on this exchange" errors gracefully

 # Copilot Instructions for CryptoExchange.Net
 
-This repository is **CryptoExchange.Net** — the base library powering 28+ cryptocurrency exchange wrappers in C#/.NET (Binance.Net, Bybit.Net, OKX.Net, Kraken.Net, Coinbase.Net, etc.).
+CryptoExchange.Net is the base library behind exchange-specific C#/.NET clients such as Binance.Net, Bybit.Net, OKX.Net, Kraken.Net, and Coinbase.Net.
 
-When generating code in this ecosystem, follow these conventions:
+## Package choice
 
-## You don't install CryptoExchange.Net directly
+Do not install CryptoExchange.Net alone to call an exchange. Install the exchange-specific package, or use `CryptoClients.Net` for the full bundle. For single-exchange code, prefer that library's native client. For portable multi-exchange code, use `CryptoExchange.Net.SharedApis`.
 
-Install the exchange-specific library you need (`Binance.Net`, `JK.OKX.Net`, `Bybit.Net`, ...) or `CryptoClients.Net` for the bundle. CryptoExchange.Net is pulled in as a dependency.
+## Generate Shared API V2 code
 
-## Multi-exchange code uses SharedApis
+Use fine-grained V2 capabilities through `.SharedApi`:
-
-For code that must work against multiple exchanges, use `CryptoExchange.Net.SharedApis` interfaces accessed via `.SharedClient` properties on each exchange's API surface:
 
 ```csharp
 using CryptoExchange.Net.SharedApis;
 
-ISpotTickerRestClient binance = new BinanceRestClient().SpotApi.SharedClient;
+IGetTickerRest binance = new BinanceRestClient().SpotApi.SharedApi;
-ISpotTickerRestClient okx     = new OKXRestClient().UnifiedApi.SharedClient;
+IGetTickerRest okx = new OKXRestClient().UnifiedApi.SharedApi;
 
 var symbol = new SharedSymbol(TradingMode.Spot, "BTC", "USDT");
-var ticker = await binance.GetSpotTickerAsync(new GetTickerRequest(symbol));
+var result = await binance.GetTickerAsync(new GetTickerRequest(symbol));
 ```
 
-Same code works on every exchange that implements the interface. Use `Task.WhenAll` for concurrent multi-exchange calls.
+Choose the interface for the operation: for example, `IGetTickerRest`, `IGetOrderBookRest`, `IPlaceSpotOrderRest`, `ICancelFuturesOrderRest`, or `ISubscribeTradesSocket`. V1 broad interfaces remain on `.SharedClient` for migration, but new code should use `.SharedApi`.
 
-## Shared symbol metadata
+Use `SharedSymbol`; do not hard-code exchange-native symbol formatting in shared code.
 
-CryptoExchange.Net 12.2.0 classifies the base and quote sides of `SharedSpotSymbol` and `SharedFuturesSymbol` with `SharedAssetType` (`Crypto`, `Fiat`, `TradFi`) and optional `SharedAssetSubType` (`StableCoin`, `Equity`, `Commodity`). The models also expose `DisplayName`. Use the corresponding base/quote fields on `GetSymbolsRequest` to filter symbol discovery.
+## Runtime capability selection
 
-`ISpotSymbolRestClient.SpotSymbolCatalog` is populated by `GetSpotSymbolsAsync`; `IFuturesSymbolRestClient.FuturesSymbolCatalog` is populated by `GetFuturesSymbolsAsync`. Do not assume a catalog is available before that request. For exchange-library implementations, `LibraryHelpers.IsStableCoin`, `IsCommodity`, and `IsEquity` offer best-effort classification and can be extended with exchange-specific values.
+When the API surface is known, assign its typed `.SharedApi` directly. When support or the API surface is selected at runtime, use the exchange-wide `I[Exchange]SharedApiClient`:
 
-## Shared market-data quantities
+```csharp
+var match = sharedClient.GetCapability(
+    SharedCapabilities.Orders.Futures.PlaceOrder.Rest,
+    TradingMode.PerpetualLinear);
 
-CryptoExchange.Net 12.4.0 uses `SharedOrderQuantity` for market-data quantities. Prefer `Volumes` on `SharedSpotTicker`, `SharedFuturesTicker`, and `SharedKline`, and `Quantities` on `SharedTrade`; the scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete.
+if (match is null)
+    return;
 
-## WebSocket order commands
+var result = await match.Capability.PlaceFuturesOrderAsync(request);
+```
 
-CryptoExchange.Net 12.5.0 adds optional `ISpotOrderManagementSocketClient` and `IFuturesOrderManagementSocketClient` interfaces for placing and canceling orders over WebSocket. These command methods return `QueryResult<SharedId>` rather than a subscription result. Check exchange support before relying on either interface.
+`GetCapability` returns one preferred `SharedCapabilityResolution<T>` or `null`; `GetCapabilities` returns all matching implementations. Include `TradingMode` when an exchange can expose multiple futures surfaces. `SharedCapabilities` entries are lookup references, not guarantees of support.
 
-## Single-exchange code uses the exchange's own client
+Before constructing dynamic requests, inspect `match.Options.RequestParameterRules`, `ExchangeParameterRules`, and `SupportedTradingModes`. A capability may exist while a particular request field is unsupported.
 
-For Binance-only code, use `BinanceRestClient` directly (see Binance.Net repo `AGENTS.md`). SharedApis is for portability — use it when you need that.
+## Results and transports
 
-## Result pattern
+- Transport-agnostic operation: `IExchangeCallResult<T>`
+- REST capability: `HttpResult<T>`
+- WebSocket command capability: `QueryResult<T>`
+- WebSocket subscription capability: `WebSocketResult<UpdateSubscription>`
 
-REST methods return `HttpResult<T>` and websocket subscription methods return `WebSocketResult<UpdateSubscription>`. Check `.Success` before `.Data`. `.Error` has structured info. `.Exchange` on shared clients identifies which exchange responded.
+Select `.Rest` or `.Socket` when transport-specific behavior matters. Otherwise exchange-wide selection uses `PreferredTransport`, normally REST. Always check `.Success` before `.Data`; use `.Error` and `.Exchange` for diagnostics.
 
-## Available shared interfaces
+## Current V2 semantics
 
-REST: tickers, symbols, orderbook, klines, trades, orders (spot/futures, trigger, TP-SL), balances, positions, fees, deposits/withdrawals, transfers.
+- Ticker operations are `GetTickerAsync` and `GetAllTickersAsync`, returning `SharedTicker` for both spot and futures.
-WebSocket: tickers, book tickers, orderbook, trades, klines, user data, and optional spot/futures order management.
+- Socket order streams use `SharedSpotOrderUpdate` and `SharedFuturesOrderUpdate`.
+- `ICloseFullPosition` closes a complete position, not a partial quantity.
+- Exchange support varies by operation, transport, trading mode, and request parameter.
 
-Each exchange library implements a subset. Check exchange docs for support matrix.
+## Engineering conventions
 
-## Avoid
+- Reuse clients through dependency injection.
+- Use `await`; never use `.Result` or `.Wait()`.
+- Use `Task.WhenAll` for independent requests across exchanges.
+- Keep exchange-native models out of portable services.
+- Do not infer feature support from a broad interface or request model.
 
-- Installing `CryptoExchange.Net` alone and trying to call exchange APIs (need exchange-specific packages)
+See `AGENTS.md`, `docs/ai-api-map.md`, and `docs/SHARED_API_V2_MIGRATION.md` for expanded guidance.
-- Mixing exchange-native models in cross-exchange code (use Shared* types)
-- Synchronous `.Result` / `.Wait()` (use `await`)
-- Instantiating clients per-request (use DI, reuse instances)
-- Sequential per-exchange calls when parallel is fine (`Task.WhenAll`)

 # CryptoExchange.Net Skill
 
 ## When to use
 
-CryptoExchange.Net is the **base library** powering 28+ exchange-specific libraries (Binance.Net, Bybit.Net, OKX.Net, Kraken.Net, Coinbase.Net, etc.). You don't install it directly — you install the exchange libraries, which depend on it.
+CryptoExchange.Net is the base library behind exchange-specific libraries such as Binance.Net, Bybit.Net, OKX.Net, Kraken.Net, and Coinbase.Net. Do not install it alone to call an exchange.
 
-**Three usage modes:**
+Choose one of these approaches:
 
-1. **You target ONE exchange** → use that exchange's library directly (e.g., Binance.Net), see its CLAUDE.md.
+1. One exchange: install and use that exchange's library directly.
-2. **You target MULTIPLE exchanges** → install each library you need + use `CryptoExchange.Net.SharedApis` interfaces — write code once, runs against any exchange. **This is the main use case for this skill.**
+2. Multiple exchanges: install the required exchange libraries and use `CryptoExchange.Net.SharedApis` V2 capabilities.
-3. **You want ALL exchanges in one package** → install `CryptoClients.Net`, get `ExchangeRestClient` and `ExchangeSocketClient` with everything bundled.
+3. All exchanges in one package: install `CryptoClients.Net` and use its combined clients and shared capability lookup.
+
+For new cross-exchange code, use Shared API V2. V1 aggregate interfaces remain available through `.SharedClient` for incremental migration.
 
 ## Installation
 
-For a multi-exchange project:
-
 ```bash
 dotnet add package Binance.Net
 dotnet add package JK.OKX.Net
 dotnet add package Bybit.Net
-# ... etc
 ```
 
-Or the bundle:
+Or install the bundle:

-## Core Pattern: Shared Interfaces
+## Core pattern: fine-grained capabilities
 
-Every exchange library exposes `.SharedClient` properties on its API surfaces. These implement the same interfaces from `CryptoExchange.Net.SharedApis`.
+Each exchange API surface exposes a typed `.SharedApi` aggregate. Assign it to the capability for the single operation being used:
 
 ```csharp

-```
 
-## Core Pattern: SharedSymbol
-
-Different exchanges format symbols differently — Binance uses `BTCUSDT`, OKX uses `BTC-USDT`, others may have other formats. `SharedSymbol` normalizes this:
-
-```csharp
-var btcusdt = new SharedSymbol(TradingMode.Spot, "BTC", "USDT");
-// Each exchange library translates SharedSymbol → its native format internally.
-
-// For futures:
-var btcusdtPerp = new SharedSymbol(TradingMode.PerpetualLinear, "BTC", "USDT");
-```
-
-For exchanges that use exotic asset names, see the AssetAliases configuration.
-
-## Symbol Metadata and Asset Classification
-
-Since CryptoExchange.Net 12.2.0, shared symbol responses describe both sides of a market with `BaseAssetType`, `BaseAssetSubType`, `QuoteAssetType`, and `QuoteAssetSubType`. `SharedAssetType` distinguishes `Crypto`, `Fiat`, and `TradFi`; `SharedAssetSubType` distinguishes `StableCoin`, `Equity`, and `Commodity`. `SharedSpotSymbol` and `SharedFuturesSymbol` also expose `DisplayName`.
-
-The same fields on `GetSymbolsRequest` filter spot or futures symbol discovery:
-
-```csharp
-var request = new GetSymbolsRequest(
-    baseAssetType: SharedAssetType.Crypto,
-    quoteAssetSubType: SharedAssetSubType.StableCoin);
-
-var result = await symbolClient.GetSpotSymbolsAsync(request);
-```
-
-After calling `GetSpotSymbolsAsync` or `GetFuturesSymbolsAsync`, use the client's `SpotSymbolCatalog` or `FuturesSymbolCatalog` to look up normalized asset and symbol metadata by name. The catalog is unavailable until the corresponding symbol request has populated the cache.
-
-For exchange-library implementations, `LibraryHelpers.IsStableCoin`, `IsCommodity`, and `IsEquity` provide best-effort classification of known assets and accept exchange-specific additions. These helpers are heuristics, not an exhaustive source of truth.
-
-## Shared Market-Data Quantities
-
-Since CryptoExchange.Net 12.4.0, shared market-data models use `SharedOrderQuantity` so base-asset, quote-asset, and contract quantities remain explicit. Read `SharedSpotTicker.Volumes`, `SharedFuturesTicker.Volumes`, and `SharedKline.Volumes`; read `SharedTrade.Quantities`. The former scalar `Volume`, `QuoteVolume`, and `Quantity` members are obsolete.
-
-## WebSocket Order Management
-
-Since CryptoExchange.Net 12.5.0, exchanges can implement `ISpotOrderManagementSocketClient` and `IFuturesOrderManagementSocketClient` to place and cancel orders over WebSocket. These are command interfaces, not subscription interfaces: `Place*OrderAsync` and `Cancel*OrderAsync` return `QueryResult<SharedId>`. Check exchange support before using them.
-
-## Available Shared Interfaces
-
-**REST:**
-
-- Market data: `ISpotTickerRestClient`, `IBookTickerRestClient`, `ISpotSymbolRestClient`, `IFuturesSymbolRestClient`, `IOrderBookRestClient`, `IRecentTradeRestClient`, `IKlineRestClient`
-- Orders: `ISpotOrderRestClient`, `IFuturesOrderRestClient`, `ISpotOrderClientIdRestClient`, `IFuturesOrderClientIdRestClient`, `ISpotTriggerOrderRestClient`, `IFuturesTriggerOrderRestClient`, `IFuturesTpSlRestClient`
-- Account: `IBalanceRestClient`, `IPositionRestClient`, `IFeeRestClient`, `ITransferRestClient`, `IDepositRestClient`, `IWithdrawalRestClient`
-
-**WebSocket:**
-
-- `ITickerSocketClient`, `IBookTickerSocketClient`
-- `IOrderBookSocketClient`, `ITradeSocketClient`, `IKlineSocketClient`
-- `IUserTradeSocketClient`, `ISpotOrderSocketClient`, `IFuturesOrderSocketClient`, `IPositionSocketClient`, `IBalanceSocketClient`
-- Order commands: `ISpotOrderManagementSocketClient`, `IFuturesOrderManagementSocketClient`
-
-Each exchange documents which interfaces it implements (some exchanges don't support every operation).
-
-## Core Pattern: Result Handling
-
-Same as exchange-specific libraries: REST calls return `HttpResult<T>` and websocket subscription calls return `WebSocketResult<UpdateSubscription>`, both with `.Success`, `.Data`, and `.Error`. Always check `.Success` first.
-
-```csharp
-var result = await sharedClient.GetSpotTickerAsync(new GetTickerRequest(symbol));
 if (!result.Success)
-{
+    Console.WriteLine($"[{result.Exchange}] {result.Error}");
-    Console.WriteLine($"[{sharedClient.Exchange}] Error: {result.Error}");
+else
-    return;
+    Console.WriteLine($"[{result.Exchange}] {result.Data!.LastPrice}");
-}
-Console.WriteLine($"[{sharedClient.Exchange}] {result.Data.LastPrice}");
 ```
 
-`.Exchange` property on every shared client tells you which exchange you're talking to — useful for logging.
+V2 interfaces describe operations, not broad feature groups. Examples include `IGetTickerRest`, `IGetOrderBookRest`, `IPlaceSpotOrderRest`, `ICancelFuturesOrderRest`, and `ISubscribeTradesSocket`. An exchange may implement one operation without implementing adjacent operations.
 
-## Core Pattern: Multi-Exchange Aggregation
+## Shared symbols
+
+Use `SharedSymbol`; never pass exchange-native symbol strings to shared requests:
 
 ```csharp
-var clients = new ISpotTickerRestClient[]
+var spot = new SharedSymbol(TradingMode.Spot, "BTC", "USDT");
-{
+var linearPerpetual = new SharedSymbol(
-    new BinanceRestClient().SpotApi.SharedClient,
+    TradingMode.PerpetualLinear,
-    new OKXRestClient().UnifiedApi.SharedClient,
+    "BTC",
-    new BybitRestClient().V5Api.SharedClient,
+    "USDT");
-};
+```
 
+Each exchange library converts the shared symbol to its native format. For unusual exchange asset names, configure asset aliases.
+
+## Known surface versus runtime selection
+
+Use the typed `.SharedApi` surface when the exchange and API are known. This is the simplest and most discoverable approach:
+
+```csharp
+IPlaceSpotOrderRest orders = restClient.SpotApi.SharedApi;
+```
+
+For runtime selection, inject the exchange-wide `I[Exchange]SharedApiClient` registered by `services.Add[Exchange](...)`. Resolve a capability with the strongly typed `SharedCapabilities` catalog:
+
+```csharp
+var match = sharedClient.GetCapability(
+    SharedCapabilities.Orders.Futures.PlaceOrder.Rest,
+    TradingMode.PerpetualLinear);
+
+if (match is null)
+    return; // This exchange/API/mode does not provide the operation.
+
+var result = await match.Capability.PlaceFuturesOrderAsync(request);
+```
+
+`GetCapability` returns one `SharedCapabilityResolution<T>` containing `Capability` and `Options`, or `null` if no supported implementation matches. `GetCapabilities` returns every match on that exchange-wide client. Always specify `TradingMode` when multiple spot, linear, inverse, or delivery surfaces could match.
+
+`SharedCapabilities` references identify interface types; they do not guarantee that an exchange implements the operation and do not send a request.
+
+## Transport selection and result types
+
+Some commands have three interfaces:
+
+- Transport-agnostic, such as `IPlaceSpotOrder`, returns `IExchangeCallResult<T>`.
+- REST-specific, such as `IPlaceSpotOrderRest`, returns `HttpResult<T>`.
+- socket-specific, such as `IPlaceSpotOrderSocket`, returns `QueryResult<T>`.
+
+Socket subscription capabilities such as `ISubscribeTickerSocket` return `WebSocketResult<UpdateSubscription>`.
+
+Use `.Rest` or `.Socket` on a capability reference when transport matters. Without a transport filter, exchange-wide lookup uses `PreferredTransport`, configured through the exchange's `SharedApi.PreferredTransport` option and normally defaulting to REST.
+
+Always check `.Success` before `.Data`. Use `.Error` for failures and the result or capability `.Exchange` value for multi-exchange logging.
+
+## Inspect parameter support
+
+The presence of a capability does not mean every shared request property is accepted by every exchange. Inspect its `CapabilityOptions`:
+
+- `RequestParameterRules`: whether each shared request field is `Required`, `Optional`, or `NotSupported`.
+- `ExchangeParameterRules`: required or optional exchange-specific values supplied through the request's `ExchangeParameters`.
+- `SupportedTradingModes`: the trading modes supported by this implementation.
+
+```csharp
+var match = sharedClient.GetCapability(
+    SharedCapabilities.Orders.Futures.PlaceOrder.Rest,
+    TradingMode.PerpetualLinear);
+
+var leverageRule = match?.Options.RequestParameterRules
+    .FirstOrDefault(x => x.Name == nameof(PlaceFuturesOrderRequest.Leverage));
+```
+
+Do not infer support from the request model alone. Handle a `null` resolution and exchange-specific parameter rules before issuing dynamic trading calls.
+
+## Common capabilities
+
+- Market data: `IGetTickerRest`, `IGetAllTickersRest`, `IGetOrderBookRest`, `IGetKlinesRest`, `IGetRecentTradesRest`; ticker, trade, kline, and order-book socket subscriptions.
+- Trading: fine-grained spot and futures place, edit, cancel, get, open-order, closed-order, and order-update capabilities.
+- Account: balances, positions, user trades, fees, deposits, withdrawals, and transfers.
+- Futures data: funding, open interest, leverage, mark price, and index price capabilities.
+
+Check the typed exchange Shared API surface or use capability lookup instead of assuming universal support.
+
+## Multi-exchange aggregation
+
+Run independent exchange requests concurrently:
+
+```csharp
+var clients = new IGetTickerRest[] { binance, okx, bybit };
 var symbol = new SharedSymbol(TradingMode.Spot, "BTC", "USDT");
 
-// Fetch concurrently from all exchanges
+var tasks = clients.Select(client =>
-var tasks = clients.Select(c => c.GetSpotTickerAsync(new GetTickerRequest(symbol))).ToArray();
+    client.GetTickerAsync(new GetTickerRequest(symbol)));
 var results = await Task.WhenAll(tasks);
 
-for (int i = 0; i < clients.Length; i++)
+foreach (var result in results.Where(x => x.Success))
+    Console.WriteLine($"{result.Exchange}: {result.Data!.LastPrice}");
+```
+
+Reuse clients through dependency injection; do not instantiate them per request.
+
+## Dependency injection
+
+Each exchange library provides `services.Add[Exchange](...)`. Registration includes its native clients, V1 shared interfaces, V2 operation capabilities, and exchange-wide shared client.
+
+Inject a capability directly only when the container has one intended implementation:
+
+```csharp
+public sealed class TickerService(IGetTickerRest ticker)
 {
-    if (results[i].Success)
+    public Task<HttpResult<SharedTicker>> GetAsync(
-        Console.WriteLine($"{clients[i].Exchange}: {results[i].Data!.LastPrice}");
+        SharedSymbol symbol,
+        CancellationToken ct = default)
+        => ticker.GetTickerAsync(new GetTickerRequest(symbol), ct);
 }
 ```
 
-## Per-Exchange Setup
+If multiple exchanges or multiple API surfaces register the same capability, inject the exchange-specific shared client and select its typed API property or call `GetCapability`. Plain single-service resolution does not express which implementation you want.
 
-Each exchange library has its own credentials class and options. See each library's CLAUDE.md for specifics. The pattern is consistent: `XxxRestClient(options => { options.ApiCredentials = new XxxCredentials(...); })`.
+For the bundle, use `services.AddCryptoClients(...)`. CryptoClients.Net provides `IExchangeSharedApiClient` for capability lookup across exchanges.
 
-## Dependency Injection
+## V1 migration
 
-Each exchange library has its own `services.AddXxx(...)` extension. They all share the same option-builder pattern. Register only the ones you use:
+V1 `.SharedClient` facades and broad interfaces such as `ISpotTickerRestClient` remain available. Migrate one operation at a time:
 
 ```csharp
-services.AddBinance(restOpts => { /*...*/ }, socketOpts => { /*...*/ });
+// V1
-services.AddOKX(restOpts => { /*...*/ }, socketOpts => { /*...*/ });
+await restClient.SpotApi.SharedClient.GetSpotTickerAsync(request);
-// Inject IBinanceRestClient, IOKXRestClient, etc.
+
+// V2
+await restClient.SpotApi.SharedApi.GetTickerAsync(request);
 ```
 
-For one-package access: `services.AddCryptoClients(...)` from `CryptoClients.Net`.
+Important semantic changes:
 
-## Common Pitfalls — AVOID
+- V2 ticker methods are `GetTickerAsync` and `GetAllTickersAsync` and return `SharedTicker` for both spot and futures.
+- WebSocket order updates use `SharedSpotOrderUpdate` and `SharedFuturesOrderUpdate`; REST order retrieval keeps the ordinary order models.
+- `ICloseFullPosition` closes the complete position. Use an order capability for partial closes where supported.
+- Transport-agnostic operations return `IExchangeCallResult<T>`; select the REST or socket interface when code needs a transport-specific result.
 
-- **Do NOT install `CryptoExchange.Net` and try to call exchange APIs directly** — it's a base abstraction; you need an exchange library.
+See `docs/SHARED_API_V2_MIGRATION.md` for detailed mappings.
-- **Do NOT try to use one exchange's models with another's client** — use the SharedApis types (`SharedSymbol`, `SharedSpotTicker`, `SharedSpotOrder`, etc.) for cross-exchange code.
-- **Do NOT block on async operations** — use `await` throughout. `Task.WhenAll` for parallelism across exchanges.
-- **Do NOT assume every exchange supports every operation** — check exchange docs or the library's implementation. Operations may return errors like "not supported on this exchange".
-- **Do NOT instantiate clients per-request** — reuse via DI.
-- **Do NOT iterate exchanges sequentially when concurrency is fine** — use `Task.WhenAll` for ~Nx speedup.
 
-## Implementing a New Exchange Library
+## Common pitfalls
 
-If you're building a NEW exchange wrapper following the CryptoExchange.Net pattern (rare but valuable):
+- Do not install `CryptoExchange.Net` alone and expect exchange endpoints.
+- Do not use `.SharedClient` for new V2 code; use `.SharedApi` and fine-grained capabilities.
+- Do not mix exchange-native request or response models into cross-exchange services.
+- Do not assume capability presence or request-parameter support; resolve and inspect it.
+- Do not rely on preferred transport when REST or socket semantics matter.
+- Do not block with `.Result` or `.Wait()`; use async calls throughout.
+- Do not query exchanges sequentially when requests are independent.
 
-- Inherit from `RestApiClient` and `SocketApiClient` base classes
+## Implementing a new exchange library
-- Define your own `XxxCredentials` extending `ApiCredentials` (or use `ApiCredentials` directly)
-- Implement `AuthenticationProvider` for the exchange's signing scheme
-- Implement the relevant `Shared*` interfaces on your API client classes for cross-exchange support
-- Follow the same `XxxRestOptions` / `XxxSocketOptions` pattern
 
-See existing libraries (Binance.Net, Bybit.Net) as reference implementations.
+- Derive API clients from `RestApiClient` and `SocketApiClient`.
+- Follow the exchange credentials and options patterns used by existing libraries.
+- Implement the relevant fine-grained V2 capability interfaces on typed Shared API classes.
+- Publish accurate `CapabilityOptions`, including supported trading modes and request/exchange parameter rules.
+- Register REST/socket Shared APIs and the exchange-wide shared client with the library's DI extension.
+- Retain V1 facades only where compatibility with existing consumers is required.
+
+Use maintained exchange libraries such as Binance.Net and Bybit.Net as implementation references.
