Binance API
Binance's REST and WebSocket API for spot, margin, and futures crypto trading with the world's highest liquidity exchange, using HMAC-SHA256 signed requests for authenticated endpoints.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
API key permissions are coarse-grained (read/trade/withdraw) — no per-symbol or per-order-type restrictions. Ed25519 signing is available and preferred over HMAC. Withdrawal IP whitelist strongly recommended.
⚡ Reliability
Best When
Your agent needs maximum liquidity, the broadest asset selection, and lowest fees for high-volume crypto trading with full futures and margin support.
Avoid When
Operating in a US-regulated context requiring FinCEN-compliant exchange; use Coinbase Advanced or Kraken instead.
Use Cases
- • Execute high-frequency spot and futures orders programmatically with low latency via REST or WebSocket order streams
- • Stream real-time order book depth, trade, and kline (candlestick) data for multiple symbols simultaneously via WebSocket
- • Monitor margin account health and automate collateral top-up to avoid liquidation events
- • Run arbitrage strategies across Binance spot and futures markets using unified account balance views
- • Implement trailing stop and OCO (one-cancels-other) orders for automated risk management without external monitoring
Not For
- • US-based users requiring a regulated exchange — Binance.US has a separate API with reduced functionality
- • Fiat on/off ramp automation — Binance's fiat APIs are heavily region-restricted and not programmatically reliable
- • Simple retail buy-and-hold portfolios where fee optimization doesn't justify the integration complexity
Interface
Authentication
Requests signed with HMAC-SHA256 using API secret; RSA and Ed25519 signature methods also supported for enhanced security. API key permissions (read, trade, withdraw) set at key creation time — no per-request scoping.
Pricing
API access is free; fees are per-trade. Holding BNB tokens provides 25% fee discount on spot trading.
Agent Metadata
Known Gotchas
- ⚠ The weight-based rate limiting system is non-obvious — agents must track cumulative request weight (not count) and parse X-MBX-USED-WEIGHT headers to avoid 429 bans
- ⚠ IP bans (418 status) are issued after repeated 429s and last minutes to days — exponential backoff alone is insufficient without weight tracking
- ⚠ Futures and spot APIs are separate base URLs (fapi vs api) with overlapping but inconsistent endpoint naming and different filter rules
- ⚠ Symbol precision rules (lot size, price filter, min notional) vary per trading pair and must be fetched from /exchangeInfo before each order to avoid PRICE_FILTER errors
- ⚠ WebSocket user data streams require a listenKey that expires every 60 minutes and must be kept alive with a keepalive PING — agents that miss this silently lose order fill events
