SDKs & Language Examples
REST is plain HTTP + JSON. Below are recommended patterns for Python, Node, and WebSocket clients.
JavaScript / Node
Browser/Node fetch works; CORS is for same-origin BFF only. Keep keys on the server in production.
WebSocket clients
Use ws or native WebSocket; send subscribe JSON; implement heartbeat, backoff reconnect, and full resubscribe.
Packaging tips
Centralize Symbol models, Base URL, and Key injection; put retry/limit logic in middleware.
