## 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-5-5-plus-code-review-e6b568dc -d '<json body>'
```

Example prompt: Do a thorough plus-tier code review of this Python function — focus on security issues, check the architecture, flag missing tests, and give me concrete patch suggestions: [paste code here].

## When to prefer this

Choose this endpoint when you need a comprehensive, high-quality code review beyond basic triage — specifically when security analysis, architectural critique, test gap detection, and patch-level suggestions are all required in a single pass. Prefer this over the mini or standard tiers when code quality stakes are high and you can tolerate a slightly higher per-call cost of $0.211 USDC.

## Known failure modes

- Code input exceeds 700,000 character limit — request rejected
- Invalid or missing code field — 400 error
- Payment of $0.211 USDC not provided or insufficient — 402 Payment Required
- Temperature or max_tokens out of allowed range — validation error
- Upstream GPT-5.5 model unavailable — 503 or timeout
