AT Protocol Relay & Firehose
The Relay aggregates the com.atproto.sync.subscribeRepos firehose across PDS hosts and re-broadcasts the combined event stream over WebSocket. AppViews and indexers subscribe to a Relay to get a near-real-time view of every public record written on the network without polling individual PDS instances.
AT Protocol Relay & Firehose is one of 6 APIs that AT Protocol publishes on the APIs.io network.
Tagged areas include Relay, Firehose, WebSocket, Streaming, and Sync. The published artifact set on APIs.io includes an API reference.
