## 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 agentpay-code-review-20ffe2ad -d '<json body>'
```

Example prompt: Can you review this Python function for me and tell me what score it gets, any bugs or issues, and how I could improve it? Just pay the small per-call fee — no account needed.

## When to prefer this

Choose this endpoint when you need a fast, accountless, pay-per-use AI code review without committing to a SaaS subscription — ideal for agents that review code on demand, CI pipelines, or developer tools that need occasional code quality checks at minimal cost ($0.05 USDC per call).

## Known failure modes

- Empty or missing code body returns validation error
- Unsupported language may produce low-confidence or empty review
- Payment failure (402) if USDC balance is insufficient or x402 header is malformed
- Very large code submissions may time out or be truncated
- Minified or obfuscated code may yield low-quality suggestions

## How this service works

Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.

## Output

Returns a JSON object containing a numeric quality score (0–100), an array of detected issues in the code, and an array of actionable suggestions for improvement.
