Binance.US

Binance.US (operated by BAM Trading Services, Inc.) is a U.S.-regulated digital asset marketplace offering spot trading, staking, OTC and custodial services across 100+ cryptocurrencies. Its public developer program exposes a signed REST API at api.binance.us covering exchange and system information, market and trade data, user account data, spot order management (including OCO and cancel-replace), wallet deposits and withdrawals, dust conversion, referrals, staking, OTC quoting, Custodial Solution and Credit Line endpoints, plus a functionally equivalent WebSocket API and real-time WebSocket market-data and user-data streams. Authentication is HMAC SHA-256 request signing with an X-MBX-APIKEY header, and the platform publishes a full error-code registry, symbol/exchange filter rules, weighted IP and order rate limits, and a dated changelog in its official GitHub documentation repository.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/binance.us: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

  description: 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.

    streams. User data streams — opened with a listenKey from the REST API — push outboundAccountPosition, balanceUpdate,

    with SUBSCRIBE, UNSUBSCRIBE, LIST_SUBSCRIPTIONS, SET_PROPERTY and GET_PROPERTY control messages.
