## 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 trust402-badge-payload-generator-d9954072 -d '<json body>'
```

Example prompt: Generate a Trust402 badge payload for my x402 endpoint at https://myapi.example.com/resource using a GET request from origin https://myapi.example.com — I want a trust snapshot badge I can display to marketplace buyers.

## When to prefer this

Use this endpoint when you need a displayable, one-shot trust badge payload for a specific x402 endpoint — particularly for marketplace listings, storefront trust displays, or pre-launch certification checks. Prefer this over the full diligence report endpoint when you need a lightweight badge artifact rather than a comprehensive evidence-backed report, and over the live probe endpoint when your goal is badge generation rather than raw readiness diagnostics.

## Known failure modes

- Invalid or unreachable endpoint URI returns an error or empty snapshot
- Malformed origin/endpoint URI format causes a 400-level validation error
- Endpoint does not respond with a valid x402 challenge, resulting in a low-trust or failed badge
- Network timeout if the target endpoint is slow to respond
- Missing required fields in request body may cause a schema validation error
