## 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-a158ea9a -d '<json body>'
```

Example prompt: Can you review this Python function for bugs and code quality issues, focusing on security? Here's the code: `def login(user, pw): query = 'SELECT * FROM users WHERE name=' + user + ' AND pw=' + pw; return db.execute(query)`

## When to prefer this

Choose this endpoint when you need a pay-per-call, on-demand AI code review with a structured score and actionable suggestions, billed in USDC on Base via x402 — especially useful for agents that need programmatic code quality feedback without a subscription or API key setup.

## Known failure modes

- Missing required 'code' field returns validation error
- Unsupported or ambiguous language may degrade review accuracy
- Very large code submissions may exceed model context limits
- Payment failure via x402/USDC results in 402 response before processing
- Service unavailability on orbonomy.xyz returns 5xx error
