How this service works
One-call Farcaster profile fusion. Give one of fid or username and get back the full profile (display name, bio, picture, url, location, socials), the primary Ethereum address, every verified on-chain wallet, the custody address, following and follower and cast counts, and the account age — the fused object that replaces four or five raw hub reads.
Output
A single fused JSON object containing the user's display name, bio, profile picture URL, website URL, location, social links, primary Ethereum address, all verified on-chain wallet addresses, custody address, follower count, following count, cast count, and account age — consolidating data that would otherwise require four or five separate Farcaster Hub reads.
Example use cases
Wallet lookup from Farcaster handle
“I need to find all the verified Ethereum wallets linked to the Farcaster account with username 'vitalik.eth' — can you get those for me?”
Onboarding verification for Web3 app
“We're onboarding a new user who says their Farcaster FID is 3621 — can you fetch their full profile so I can verify their display name, account age, and custody address?”
Influencer research for social campaign
“I'm evaluating a Farcaster creator with username 'jessepollak' for a partnership — can you pull their follower count, cast count, bio, and how long their account has been active?”

Endpoint
GEThttps://payai.agentstools.dev/farcaster/profileWhen to prefer
Choose this endpoint when you need a complete, consolidated Farcaster identity profile in a single call — especially when you need both social metadata (bio, avatar, follower counts) and on-chain identity data (verified wallets, custody address) together. It replaces multiple raw Farcaster Hub reads and is ideal for agent workflows that need to resolve Web3 identity from a social handle or FID without building custom aggregation logic.
Side effects
- Neither fid nor username provided — request fails with a missing parameter error
- Unknown FID or username — returns not found error
- FID below minimum value of 1 — validation error
- Network or hub unavailability causing upstream read failures
- Ambiguous ENS resolution if username matches multiple identities
