## 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 nova-ai-code-review-api-e3ef61b6 -d '<json body>'
```

Example prompt: Can you review this Python function for bugs and best practice violations — focus on security — and give me a quality score with a list of issues to fix?

## When to prefer this

Choose this endpoint when you need AI-powered code review with a structured output (score + issues + suggestions) on a pay-per-call basis using USDC on Base, and you want automatic language detection without configuring a full static analysis pipeline.

## Known failure modes

- Missing required 'code' field returns validation error
- Payment of 0.1 USDC on Base not completed results in 402 Payment Required
- Unsupported or ambiguous language may reduce review quality
- Very large code submissions may hit token or size limits
- Network timeout for unusually complex codebases

## How this service works

Pay-per-call AI inference. Chat, reason, translate, analyze, generate. USDC on Base.

## Output

Returns a structured review object containing an integer quality score, an array of detected issues, a plain-language summary, and an array of actionable suggestions, along with metadata about the detected language, focus area, model used, and token usage.
