## 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 synthex-forge-code-review-brief-b6a329be -d '<json body>'
```

Example prompt: Can you give me a code review brief for this Python snippet: `def add(a, b): return a + b` — I need a concise summary of any issues or improvements?

## When to prefer this

Choose this endpoint when you need a fast, cryptographically signed code review brief — especially for compliance, audit, or governance workflows where an Ed25519-attested artifact is required. Prefer this over generic LLM code review when you need a verifiable, on-chain-payable attestation on Base mainnet rather than an informal suggestion.

## Known failure modes

- Missing or empty 'code' field returns an error response
- Unsupported or unrecognized 'language' value may degrade review quality
- Payment not provided or insufficient USDC results in HTTP 402 payment-required response
- Malformed JSON body returns a 400 bad request
- Extremely large code snippets may be rejected or truncated
- Network timeout if the signing/attestation backend is slow

## How this service works

Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.

## Output

Returns a JSON object with ok: true and a concise code review brief containing analysis, findings, and suggestions for the submitted code snippet, signed with Ed25519 and SHA-256 per the Synthex Forge attestation standard.
