Binance.US WebSocket API is one of 3 APIs that [Binance.US](https://apis.io/providers/binance.us/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include Cryptocurrency, Exchange, Trading, Real-Time, and WebSocket. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

The Binance.US WebSocket API is a request/response API delivered over a persistent WebSocket connection at wss://ws-api.binance.us/ws-api/v3. It is functionally equivalent to the REST API — the same parameters, the same status and error codes — but offers lower latency for time-sensitive trading. It covers general requests, market data requests, trading requests (place/test/query/cancel/replace orders and OCO), account requests, and user data stream lifecycle requests. SIGNED (TRADE and USER_DATA) requests use the same HMAC SHA-256 signature and timing rules as the REST API.
