API for Developers

Connect your bots,
your way

REST for orders and account state, WebSocket for live order-book and trade streams. Scoped API keys, IP allowlists, and a generous rate-limit budget for retail bots and market makers alike.

Quick start

Place your first order in five lines

# place a limit buy order — 0.01 BTC @ $63,000

Core REST endpoints

GET /v1/markets List all trading pairs with status, tick size and minimum order size.
GET /v1/ticker/{pair} Latest trade, best bid/ask, 24-hour change, volume and market cap.
GET /v1/orderbook/{pair} Current order book (depth-100 by default, depth-1000 for verified accounts).
POST /v1/orders Create a limit, market or stop order. Returns the order ID and current state.
GET /v1/orders/{id} Fetch order status, average fill price and remaining size.
POST /v1/orders/{id}/cancel Cancel an open order. Idempotent — safe to call from a retry loop.
GET /v1/account/balances Spot, margin and earn-product balances broken out by asset.

The boring API features that actually matter

Sane rate limits, idempotent cancels, scoped keys. The things you wish every exchange API had.

  • Per-key rate limit: 1,200 weighted req/min for retail, higher tiers for verified market makers
  • WebSocket order-book and trade streams with delta-only updates after the initial snapshot
  • Scoped keys: read-only, trade-only or trade+withdraw — pick what your bot actually needs
  • IP allowlist on every key — request from outside the list returns 403 with a clear error code
  • Idempotent client_order_id — safe to retry orders without double-spending
  • HMAC-signed requests with a clock-drift tolerance you can configure per key
  • Sandbox environment with realistic market data and testnet balances — same code path as prod
  • OpenAPI 3.0 spec available — generate clients in your language of choice
