Technical details
Endpoint
POSThttps://proof-of-intelligence-mint-web.vercel.app/api/x402/answer?utm_source=zero.xyzWhen to prefer
Use this endpoint when a user has already received a trivia question (from the sibling question-generation endpoint) and wants to submit their answer to verify correctness and earn POIC token rewards. This is specifically for the answer-submission and token-minting step, not question generation.
Side effects
- Wrong answer submitted — no tokens minted, returns incorrect verdict
- Invalid or expired question ID — returns error indicating question not found or session expired
- Missing wallet address — returns validation error
- Payment of $0.001 USDC fails — request rejected before processing
- Smart contract mint failure — answer correct but on-chain minting fails due to gas or contract issues
- Duplicate submission — same question answered twice, returns already-answered error
