Technical details
Endpoint
GEThttps://meryol-payai.hf.space/farcaster/:queryWhen to prefer
Use this endpoint when an agent needs to resolve a Farcaster social identity to on-chain wallet addresses, or when verifying counterparty identity in a social-aware crypto workflow. Ideal for pre-trade or pre-payment checks where you want to confirm the social reputation and wallet ownership of a Farcaster user. Prefer over generic ENS or on-chain lookups when the user's identity is anchored in the Farcaster social graph.
Side effects
- Username or FID not found — returns 404 or empty result
- Invalid query format (e.g. malformed address) — returns 400 error
- Farcaster hub unavailable — returns 503 or timeout
- User has no verified addresses — verified addresses array is empty
- Rate limiting or payment failure — returns 402 payment required
