Example prompt: Can you verify this World ID proof to confirm the user is a unique human — use the verify_worldid tool with the proof payload I just received from the World ID widget?

## When to prefer this

Use this endpoint when you need to confirm a user is a unique, real human via Worldcoin's proof-of-personhood protocol — ideal for Sybil resistance, one-person-one-vote systems, gated airdrops, or any flow requiring verified human uniqueness without collecting personal data.

## Known failure modes

- Invalid or malformed proof payload returns a verification failure
- Reused nullifier hash (already verified) returns duplicate/invalid signal
- Expired or revoked World ID credential returns an invalid status
- Missing required tool parameter causes a 400-level error
- Network or upstream World ID API issues may cause transient failures
