## 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 x402-tools-unscored-row-diagnostics-eb25ddeb
```

Example prompt: Run a diagnostic fetch against the x402 unscoredrow SKU endpoint using a GET request to openclawproductions.com and show me the paid JSON payload it returns after payment clears through OpenX402.

## When to prefer this

Choose this endpoint when you need to test, validate, or demonstrate x402 HTTP payment gating using the OpenX402 facilitator specifically. It is ideal for developers integrating x402 micropayments into their own APIs who want to inspect the paid JSON payload shape, the HTTP 402 error structure, and EIP-3009 extras in a controlled diagnostic context rather than a production endpoint.

## Known failure modes

- HTTP 402 returned if payment via OpenX402 facilitator is missing or invalid — response includes EIP-3009 payment extras
- Non-GET/HEAD/DELETE HTTP methods rejected by input schema validation
- Invalid or unreachable origin URL may cause request failure
- OpenX402 facilitator unavailability blocks payment settlement

## 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 ('unscoredrow'), a human-readable title ('Unscored Row'), the price ('$0.02'), and a diagnostic note confirming the paid shape. Unpaid requests return HTTP 402 with EIP-3009 payment metadata.
