Technical details
Endpoint
POSThttps://proof-of-intelligence-mint-web.vercel.app/API/x402/answer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to submit a trivia answer and automatically receive POIC token rewards on-chain if correct. Prefer this over the question-generation sibling endpoint when the question has already been fetched and you are ready to submit a response. Ideal for gamified AI agent workflows that combine knowledge verification with on-chain token incentives.
Side effects
- Incorrect answer submitted — no tokens minted, returns failure verdict
- Invalid or missing question ID — 400 error or unrecognized question
- Wallet address missing or malformed — minting fails
- Payment not received or insufficient — request rejected before processing
- Question already answered or expired — idempotency or timing conflict
- Smart contract or minting service error — tokens not issued despite correct answer
