## 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-x402-claim-proof-diagnostic-ea7d05d6
```

Example prompt: Can you retrieve the claimproof diagnostic from the OpenClaw x402 tools — I want to confirm my EIP-3009 payment authorization goes through and get back the signed claim proof JSON.

## When to prefer this

Use this endpoint when you need to verify that an x402 micropayment flow — specifically using EIP-3009 and the OpenX402 facilitator — is working correctly end to end. It is the right choice for testing, debugging, or auditing x402 payment integrations at the claimproof SKU level, not for general content retrieval or non-crypto payment validation.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras if payment is missing or invalid — indicates unpaid or malformed micropayment
- Invalid or expired EIP-3009 authorization token causes payment rejection
- Wrong facilitator (non-OpenX402) may result in payment not being recognized
- Malformed request properties field may yield unexpected or empty response
- Network timeout or service unavailability returns no diagnostic payload

## How this service works

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

## Output

Returns a JSON object containing the SKU name ('claimproof'), a human-readable title ('Claim Proof'), the price ('$0.03'), and a diagnostic note confirming the paid JSON shape. This serves as proof that the x402 payment was accepted and the EIP-3009 authorization was valid.
