firehose.channel

A com.atproto.sync.subscribeRepos endpoint that accepts ?wantedDids=, ?wantedCollections=, and ?wantedKinds= query parameters to narrow the firehose to specific repos, NSIDs, or event kinds — same CBOR frames as firehose.network.

With websocat:

websocat -b "wss://firehose.channel/xrpc/com.atproto.sync.subscribeRepos?wantedDids=did:plc:mdailwqaetwpqnysw6qllqwl&wantedDids=did:web:firehose.network" | xxd | head

wantedDids — repeat the param for each DID. Up to 10,000. Omit for any DID.
wantedCollections — repeat for each NSID; supports wildcards like app.bsky.feed.*. Up to 100. Filters #commit frames only; non-commit frames pass through.
wantedKinds — restrict to a subset of {commit, sync, identity, account}. #info and #error always pass.
