# Nova AI Code Review API

> Nova AI Code Review API is a paid API for AI agents from novva.orbonomy.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Performs AI-powered code review, returning a quality score, identified issues, and improvement suggestions for submitted source code.

## 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-3d2798d6 -d '<json body>'
```

Example prompt: Can you review this Python function for bugs and performance issues — give me a score, a list of problems, and suggestions to fix them?

## When to prefer this

Choose this endpoint when you need a structured, scored code review with explicit issues and suggestions — especially when the result must be machine-readable (score + issues array). Prefer it over generic AI chat for code review when you need consistent JSON output format and pay-per-call economics without a subscription.

## Known failure modes

- Missing required 'code' field returns an error response with success: false
- Empty or extremely short code snippets may produce low-quality reviews
- Unsupported or obscure languages may result in inaccurate auto-detection
- Payment failure (insufficient USDC on Base) blocks the call entirely
- Rate limiting or server errors may return non-200 HTTP responses

## How this service works

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

## Output

Returns a structured code review object containing a numeric quality score (integer), a list of detected issues, a plain-language summary of the review, and an array of actionable suggestions, along with metadata including the detected language, model used, token usage, and timestamp.
