Api Endpoint

farcaster-resolve

Bidirectional Farcaster identity and wallet resolver. Give an address to get the FID it belongs to (custody address resolves keyless; a verified address needs the optional enrichment), or give a fid or username to get the canonical identity (fid, username, custody address and verified wallets). Crypto-native reconciliation of social identity and wallet.
