## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability proof-of-intelligence-answer-trivia-mint-poic-tokens-87aa6c85 -d '<json body>'
```

Example prompt: Submit my answer 'Marie Curie' to the current Proof of Intelligence trivia question and mint POIC tokens to my wallet if it's correct.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

Submit answer to trivia question and mint POIC tokens if correct. Minimal payment for x402scan visibility.

## Output

Returns whether the submitted answer was correct, and if so, confirms that POIC tokens have been minted to the caller's wallet address, along with transaction details or token balance update.
