Output
Returns a structured JSON object with the user's Farcaster ID, bio, display name, follower/following counts, engagement rate, inferred interest tags, top channels, verified Ethereum addresses, power badge status, activity status, a composite account quality score (0-100), a Neynar reputation score (0-1), a reputation label (high/medium/low/spam), and a one-line agent-readable summary.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://farcaster-intel-api.vercel.app/api/user?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, agent-optimized Farcaster user intelligence in a single call, especially when you need reputation scoring, inferred interests, or verified wallet address resolution. Prefer this over raw Farcaster/Neynar APIs when you want pre-processed, normalized output designed for AI agent consumption with pay-per-query pricing.
Side effects
- Username not found — returns 404 or empty result if the Farcaster username does not exist
- Missing username parameter — returns 400 bad request if 'username' is not provided
- Payment failure — x402 payment in USDC on Base not processed, returns 402 Payment Required
- Rate limiting — too many requests may result in throttling
- Stale data — profile data may lag behind real-time Farcaster state if caching is in place
