## 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 humanmirror-x402-payment-compatibility-receipt-e06fe0a3

Example prompt: Can you check whether my last x402 payment to HumanMirror went through and get me the compatibility receipt showing it was verified successfully?

## When to prefer this

Use this endpoint when you need to confirm that an x402 micropayment to HumanMirror was processed and obtain a machine-readable receipt for audit, logging, or workflow gating purposes. Prefer this over generic payment status checks when working specifically within the x402 protocol ecosystem and the HumanMirror trust infrastructure.

## Known failure modes

- Payment not yet processed — returns a non-verified status or ok:false
- Invalid or missing query parameters — may return 400 or an error JSON
- Network timeout or service unavailability from humanmirror.fr
- Payment amount mismatch — receipt not issued if 0.001 USDC was not received
- x402 protocol version incompatibility — endpoint may reject unsupported protocol variants
