Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 whatchuneed-llm-code-review-7b364bd8 -d '<json body>'
```

Example prompt: Can you review this Python function for me and flag any bugs, bad practices, or places I could improve it? The task is to parse a CSV file and return a list of dicts.

## When to prefer this

Choose this endpoint when you need a structured, machine-readable code review with per-line issue tracking and severity ratings — especially useful for automated CI pipelines, agent-driven development workflows, or when you need programmatic access to code quality feedback. Prefer this over general LLM chat for code because the output is schema-structured with explicit issues array and line numbers rather than free-form prose.

## Known failure modes

- Missing required 'code' field returns validation error
- Very large code submissions may time out or be truncated
- Unsupported or ambiguous language may produce generic or inaccurate feedback
- Payment failure via x402 protocol returns 402 status with no result
- Malformed JSON body returns 400 error
