## 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 gpt-5-4-mini-standard-code-review-aa3982fe -d '<json body>'
```

Example prompt: Can you do a standard code review of this JavaScript function for bugs, edge cases, and missing tests? Focus on error handling and use up to 2048 output tokens: `function divide(a, b) { return a / b; }`

## When to prefer this

Choose this endpoint when you need a fast, affordable AI code review paid per-call via USDC micropayment on Base without a subscription. Ideal for agents that process code snippets or modules on-demand and need structured feedback on bugs, edge cases, and test coverage. Prefer this over general chat completions when you want a purpose-scoped review prompt rather than crafting your own.

## Known failure modes

- Code input exceeds 700,000 character limit — request rejected
- Payment via x402 USDC on Base fails or is insufficient (min $0.00293) — 402 response returned
- Invalid language or focus parameter — may produce generic or misaligned review
- Empty or whitespace-only code string — rejected due to minLength:1
- Model unavailability upstream — 503 or timeout error
