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
A list of all cryptographically verified wallet addresses (Ethereum and Solana) linked to the given Farcaster identity, the in-profile primary Ethereum address, and provenance metadata indicating how each address was verified — covering the full forward identity-to-wallet resolution.
Example use cases
Example prompt
“What verified on-chain wallet addresses are linked to the Farcaster user 'vitalik.eth'? I need both their Ethereum and Solana addresses and want to know which one is their primary.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/farcaster/verificationsWhen to prefer
Use this endpoint when you need to go from a known Farcaster social identity (FID or username) to their verified on-chain wallets — ideal for reputation checks, airdrop targeting, provenance work, or enriching a Farcaster profile with blockchain identity. Prefer over general ENS resolvers when the identity is Farcaster-native and you need Solana addresses or full verification provenance, not just a primary ENS name.
Side effects
- FID or username not found — returns 404 or empty result
- Neither fid nor username provided — returns 400 bad request
- Username provided without at-sign but still invalid format — validation error
- Farcaster user exists but has no verified addresses — returns empty verifications list
- Network/upstream Farcaster hub unavailable — returns 503 or timeout
- Payment not attached or insufficient — returns 402 Payment Required
