Technical details
Endpoint
GEThttps://api.web3identity.com/api/farcaster/dwrWhen to prefer
Use this endpoint when you need to resolve a Farcaster identity from any of the three lookup keys — FID, username, or connected wallet address — especially in Web3 contexts where you need to bridge on-chain addresses to Farcaster social profiles. Prefer over scraping Warpcast directly for reliable structured data.
Side effects
- User not found for given FID, username, or address returns 404 or empty result
- Invalid or malformed address/FID returns 400 bad request
- Rate limiting or payment failure returns 402 or 429
- Farcaster API upstream unavailability causes 503 or timeout
