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.
