ProtocolWebSocketTransportOptions

Headers applied to every request.

The configured API key, when present, is added as the x-api-key header after these defaults are initialized.

Maximum reconnect attempts after an unexpected SSE disconnect. Defaults to 5. Set to 0 to disable automatic reconnection.

Called before each SSE reconnect attempt (after backoff delay).

Invoked after the socket has been re-established. Use to restore server-side subscription state (see ThreadStream).

Hook for inspecting or mutating a request before it is sent.

Receives the resolved URL and prepared RequestInit; return the original init or a replacement object to continue the request.

Override the default /threads/:threadId/... protocol paths.

Backoff before each SSE reconnect attempt. Defaults to webSocketReconnectDelayMs from ./websocket.js.

Thread ID this transport currently targets.

Optional WebSocket factory. Supplying it flips the adapter into WebSocket mode — SSE is bypassed entirely.
