WebSocket channels

After connecting, send a subscribe payload:

{
  "type": "subscribe",
  "channels": ["ticker:BTCUSDC", "trades:ETHUSDC"]
}

Available channels:

  • ticker:<SYMBOL> — price, bid/ask, 24h volume
  • trades:<SYMBOL> — recent fills
  • orderbook:<SYMBOL> — book snapshot + delta
  • orders:user — events for your orders (auth)
  • balances:user — balance updates (auth)

Authenticated API keys

For trading and account operations, generate an API key at /api-keys with a specific scope:

  • read — read balances, orders and history
  • trade — open, cancel and modify orders
  • withdraw — request withdrawals (rare scope, additional gate)

Authentication via the X-OFFCODE-Key header + HMAC signature of the payload. Technical questions? Contact support.

Rate limits

  • Public: 60 req/min per IP
  • Authenticated: 600 req/min per API key
  • WebSocket: 100 subscribes per connection, no limit on inbound messages

The X-RateLimit-Remaining response header indicates remaining calls. Exceeding it returns HTTP 429 with Retry-After.

Risk warning. Programmatic trading amplifies execution speed and risk. Poorly configured bots can generate losses quickly. This documentation does not constitute investment advice. Test extensively before trading with real capital.
