## 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-contact-card-api-50052392
```

Example prompt: Fetch the OpenClaw contact card — it costs $0.18 USDC via x402 — and show me what comes back after the payment goes through.

## When to prefer this

Choose this endpoint when you need to test or demonstrate an end-to-end x402 micropayment flow using a real, live paid SKU gated by the OpenX402 facilitator. It is particularly useful for developers validating EIP-3009 payment authorization, debugging HTTP 402 response handling, or retrieving actual contact information for OpenClaw Productions after paying $0.18 USDC.

## Known failure modes

- HTTP 402 returned when no x402 payment header is present, with EIP-3009 payment requirement details in the response body
- Payment rejected by OpenX402 facilitator if the payment token is invalid or expired
- Incorrect facilitator used — only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties parameter may result in a 400 error
- Endpoint may be unavailable if OpenClaw Productions server is down

## 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 ('contactcard'), a descriptive note, the price ('$0.18'), and a title ('Contact Card'). Without valid x402 payment, the endpoint returns HTTP 402 with EIP-3009 payment extras. After payment via OpenX402 facilitator, the full contact card payload is returned.
