WebSocket Streaming — Live Quotes

Open a single connection, subscribe to a symbol list, and receive every bid/ask update push-style. No polling, no wasted requests — ideal for dashboards, alert engines, and execution bots that need quotes the instant they change.

Status: Live on the Starter plan and above. Pay-as-you-go keys cannot open the stream; on pay-as-you-go, use the REST /v1/quote endpoint for polling-based price reads.

        ws.send(json.dumps({
            "action": "subscribe",

Connection lifecycle

  1. Connect to wss://tickatlas.com/ws/v1/quotes. The API key is not a URL parameter.
  2. Send {"action": "auth", "key": "YOUR_API_KEY"} as the first message. You have 10 seconds; after that the server closes the socket with code 4001.
  3. Wait for the authenticated frame, then send a subscribe message with the symbol list.
  4. Receive a quote message every time a subscribed symbol changes.
  5. Send unsubscribe or close the socket when done.

Heads up: WebSocket streaming requires the Starter plan or higher and is unmetered: pushes do not count against your quota. See the WebSocket LP for per-plan symbol limits.
