## 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-code-review-triage-mini-tier-40297b53 -d '<json body>'
```

Example prompt: Can you do a quick code review triage on this Python function for obvious bugs, lint risks, and missing tests? Here's the code: `def divide(a, b): return a / b` — focus on error handling and keep the response under 500 tokens.

## When to prefer this

Choose this endpoint when you need fast, cheap AI-assisted code review triage for a single code snippet and want structured feedback on bugs, lint risks, and missing tests without running a full static analysis pipeline. Ideal for pre-commit checks, PR triage, or quick sanity checks where cost sensitivity matters and a mini-tier model is sufficient.

## Known failure modes

- Input code exceeds 700,000 character limit — request rejected
- max_tokens exceeds 4096 — validation error
- Empty or missing code field — request rejected
- Payment failure or insufficient USDC balance via x402 — 402 response
- Temperature out of range (0–2) — validation error
- Upstream model unavailable — 5xx error

## How this service works

Fast code-review triage for obvious bugs, lint risks, and missing tests. Model tier: mini; upstream model: gpt-5.4-mini. Price is derived from official OpenAI relative token costs with a local margin and floor. Pay up to $0.003232 per request with x402 USDC on Base. Public paid calls are limited to 700000 input characters and 4096 output tokens.

## Output

Returns an AI-generated code review identifying obvious bugs, lint risks, and missing test gaps in the submitted code, up to 4096 output tokens. Response is scoped to the provided focus area and language context.
