## 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 agent-json-reliability-evidence-receipt-11bdacbb -d '<json body>'
```

Example prompt: Can you fetch the payment receipt for my last Reliable JSON API call so I have evidence the 0.003 USDC x402 payment on Base was accepted?

## When to prefer this

Use this endpoint when you need to programmatically verify or log proof that a prior x402 micropayment for the Reliable JSON service was successfully received. It is the dedicated receipt/attestation endpoint for this service's payment flow, not a general payment lookup tool.

## Known failure modes

- No matching payment record found — returns an error if the payment reference is invalid or not yet settled
- Payment not yet confirmed on Base — may return a non-ok response if the blockchain transaction is still pending
- Invalid or missing request body — returns a 400-level error if required payment proof fields are absent
- Service unavailable — Render.com hosting may cause cold-start delays or temporary 503 errors
