## 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-watch-provider-verify-4a92f9aa -d '<json body>'
```

Example prompt: Can you verify whether https://example-watch-provider.com is a legitimate watch provider endpoint using the Genesis machine utility?

## When to prefer this

Use this endpoint when you need to programmatically confirm whether a given URL is a recognized watch provider before integrating it into an agent workflow. It is specifically designed for the GENESIS* Watch ecosystem and machine-to-machine provider discovery, so prefer it over generic URL health checks or ping utilities when provider legitimacy and machine discoverability matter.

## Known failure modes

- Invalid or malformed URL returns an error or non-verification response
- Provider URL is unreachable or returns non-standard responses, causing verification failure
- Payment not fulfilled via x402 results in 402 Payment Required response and no verification
- URL is syntactically valid but not a watch provider, likely returning machine_discovery: false or an error check value
- Network timeout if provider URL is slow to respond

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

Returns a JSON object with a 'check' field confirming 'provider_verification', a 'product' field identifying the GENESIS* Watch product, and a 'machine_discovery' boolean indicating whether the provider URL supports autonomous machine discovery.
