Get rich recent airings and current queue evidence for a PoolParty channel. Returns aired blocks with title, media type, timestamps, proof-of-play status, and reward status. Also returns current queue positions with mintStatus and poolEligibility so agents can distinguish pre-mint, mint-pending, minted, pool-eligible, and ineligible blocks. get_channel_feed is a rich feed and may be large. Use it for diagnostic recent airing and queue evidence, mintStatus, poolEligibility, proof, and reward readbacks. For first-pass channel awareness, use get_channel_stream(channelSlug="main", limit=10) or the REST /api/channels/main/activity snapshot; use /api/channels/main/activity/stream when an SSE watch is intended. Read-only. No auth required.
