## 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 uos-genesis-machine-passport-verify-000de05c -d '<json body>'
```

Example prompt: Can you verify whether Genesis Machine Passport ID GMP-EXAMPLE is valid and confirmed?

## When to prefer this

Use this endpoint when you need to confirm the validity of a UOS Genesis Machine Passport identifier before granting access, onboarding a machine, or trusting a machine agent's claimed identity. It is specifically designed for the UOS/Genesis Machine ecosystem and is not a general-purpose identity verification service.

## Known failure modes

- Missing or malformed passport_id field returns an error response
- Unrecognized passport_id returns verified: false
- Network or worker-side failure returns success: false
- Invalid JSON body structure causes a 400-level error
- Payment failure via x402 prevents the call from completing

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

Returns a JSON object with a 'success' boolean indicating whether the request succeeded, a 'verified' boolean indicating whether the passport ID is valid and verified, and the 'passport_id' string that was checked.
