## 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 x402-payment-receipt-verifier-af144c11 -d '<json body>'
```

Example prompt: Can you verify that my x402 payment settled? The tx hash is 0xabc123... on the base network — I want to confirm it went through and see the amount and addresses.

## When to prefer this

Use this endpoint when you need to verify that a specific x402 micropayment has settled on-chain given a known transaction hash and network. It is purpose-built for the x402 payment protocol ecosystem and returns structured receipt data (status, amount, from/to, block) rather than raw blockchain data. Prefer this over generic blockchain explorers when operating within an x402-enabled agent workflow where you need a clean, structured confirmation before proceeding.

## Known failure modes

- Transaction hash not found on specified network — returns not found or null status
- Invalid or malformed tx hash — returns validation error
- Network identifier unrecognized — returns bad request error
- Transaction still pending — status returned as pending with no block data
- RPC node unavailable for the specified network — returns upstream error

## How this service works

Verify an x402 payment settled: tx hash -> status, amount, from/to, block

## Output

Returns the on-chain settlement status of the transaction (e.g. confirmed, pending, failed), the payment amount, the sender and recipient wallet addresses, and the block number in which the transaction was included.
