Realtime WebSocket API
SEC Filings – WebSocket API
The WebSocket endpoint provides a real-time stream of SEC filings discovered by our platform. As soon as the connection is open, the server sends a short backlog of the most recent filings and then pushes every new filing with an average latency of 100 ms.
Implemented Standards:
caution
Your WebSocket client implementation must comply with the "v13" version of the protocol documented in the RFC6455, including responding with the Pong message each time we send Ping (every minute). Failure to respond results in the connection being closed.
Authentication
The stream requires the same API key as the rest of the FinFeed SEC API platform. Refer to the authentication section for detailed instructions.
