## 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 openclaw-agent-attest-x402-diagnostics-bce6d97a
```

Example prompt: Run the OpenClaw Agent Attest diagnostic to confirm my x402 payment stack is working — go ahead and settle the $0.20 USDC charge via OpenX402 and show me the attestation result.

## When to prefer this

Choose this endpoint when you need to verify that an AI agent's x402 HTTP payment stack is correctly configured end-to-end, specifically when using the OpenX402 facilitator and EIP-3009 transfer authorization. It is not a production data service — its primary value is as a live payment-gated diagnostic probe.

## Known failure modes

- HTTP 402 returned if payment header is missing or invalid — response includes EIP-3009 extras for retry
- Payment rejected by OpenX402 facilitator if wrong facilitator is used — only OpenX402 is supported
- Malformed or missing authorization signature causes payment failure
- Network timeout if USDC settlement confirmation is slow

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

A JSON object containing the SKU identifier ('agentattest'), a human-readable title ('Agent Attest'), the price ('$0.20'), and a diagnostic note confirming the paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment details instead.
