How this service works
Resolve a Farcaster identity to its verified on-chain wallets. Give one of fid or username and get every cryptographically verified address (Ethereum and Solana) linked to that FID, plus the in-profile primary Ethereum address and provenance. The forward identity to wallet direction for reputation and provenance work.
Output
Returns all cryptographically verified Ethereum and Solana wallet addresses linked to the given Farcaster FID or username, the in-profile primary Ethereum address, and provenance information indicating how each address was verified.
Example use cases
Airdrop wallet resolution for Farcaster users
“I want to airdrop tokens to my top Farcaster followers — can you pull all their verified Ethereum wallet addresses? Start with FID 3 and FID 1317.”
On-chain reputation check for a creator
“Before I commission this Farcaster creator, can you check what verified wallets are linked to their username 'horsefacts' so I can verify their on-chain activity?”
Cross-platform identity linking
“I need to tie the Farcaster profile 'dwr.eth' to their actual blockchain wallets — pull all their cryptographically verified Ethereum and Solana addresses including the primary one.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/farcaster/verificationsWhen to prefer
Choose this endpoint when you need the forward direction of Farcaster identity resolution — going from a known Farcaster identity (FID or username) to verified wallet addresses. It is ideal for airdrop targeting, on-chain reputation checks, payment routing to Farcaster users, and provenance verification. Prefer this over generic ENS resolvers when the identity is specifically a Farcaster profile, as it returns all verified addresses (including Solana) plus provenance, not just a primary ENS-linked address.
Side effects
- FID not found — returns empty or error if the FID does not exist
- Username not found — unrecognized fname or ENS returns an error
- Neither fid nor username provided — missing required query parameter causes a 400-level error
- Rate limit or payment failure — x402 payment not accepted results in 402 response
- Farcaster node unavailable — upstream Farcaster hub timeout causes 5xx error
