How this service works
Trending Farcaster channels ranked by casting activity over 1d, 7d or 30d, with cast counts for all three windows, follower and member counts, and the channel lead. Cached 60 s. Use to spot where attention is moving on Farcaster right now, then pull the feed with fc-channel-feed.
Output
A JSON object containing an array of trending Farcaster channel objects, each with channel ID, name, Warpcast URL, image URL, cast counts broken down by 1d/7d/30d windows, member count, follower count, lead user profile, moderator FIDs, creation date, description, and public casting status. Also includes pagination cursor (nextCursor), total count, the active time window, fetch timestamp, and rate limit metadata (limit, remaining, resetAt).

It is purpose-built for agents operating in the Farcaster/web3 social ecosystem via x402 pay-per-call with no API key required.
