Real-time price WebSocket
Upgrade to a WebSocket connection for real-time coin price ticks.
Auth: Pass your API key as ?key=<api-key> in the query string
(browser WebSocket clients cannot set arbitrary headers).
Client → server messages:
{ "op": "subscribe", "symbols": ["btc", "eth"] }
{ "op": "subscribe", "symbols": ["*"] }
{ "op": "ping" }
Server → client messages:
{ "op": "snapshot", "as_of": 1751584800, "coins": [ ...CoinMarket objects... ] }
{ "op": "tick", "as_of": 1751585100, "changes": [
{ "symbol": "btc", "price": 62800.00, "pct_24h": 2.5, "direction": "raise" },
{ "symbol": "eth", "price": 1740.00, "pct_24h": -0.8, "direction": "fall" }
]}
{ "op": "pong" }
Limits: 10 concurrent connections per merchant. Slow consumers have individual ticks dropped (they are not disconnected).
