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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. 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.

  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,
    executionReport and listStatus events. Streams can be consumed raw at /ws/streamName or combined at /stream?streams=,
    with SUBSCRIBE, UNSUBSCRIBE, LIST_SUBSCRIPTIONS, SET_PROPERTY and GET_PROPERTY control messages.
