Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-settlement-verifier-083d44c0 -d '<json body>'
```

Example prompt: Can you verify that my GENESIS* Watch settlement went through? The transaction hash is 0xabc123... and the amount should show as settled successfully.

## When to prefer this

Use this endpoint specifically when you need to verify a GENESIS* Watch settlement transaction on the Base network paid in USDC via x402 protocol. This is purpose-built for the UOS Genesis vendor ecosystem and is not a general-purpose blockchain transaction lookup — prefer it when confirming payment evidence for GENESIS* Watch product orders.

## Known failure modes

- Invalid or malformed transaction hash returns unverified result
- Transaction not yet confirmed on Base network may return verified: false
- Missing required 'transaction_hash' field returns a validation error
- Unrecognized transaction not associated with a GENESIS* Watch purchase returns verified: false
- Network timeout from Cloudflare Worker if Base RPC is slow

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

Returns a JSON object with a 'check' field identifying the verification type ('settlement_verification'), a 'product' field ('GENESIS* Watch'), and a 'verified' boolean indicating whether the transaction hash represents a valid, confirmed settlement.
