## 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-find-price-meters-86fbbff6
```

Example prompt: Can you check what the x402 price meter looks like for a GET request to https://example.com/api/data — I want to know the SKU, price, and title before I try to pay for it.

## When to prefer this

Use this endpoint when you need to discover x402 payment gate metadata (price, SKU, title) for an HTTP resource before committing to a payment. It is the right choice when building payment-aware agents that need to pre-flight the cost of calling a paywalled API, audit x402 monetization on a domain, or integrate EIP-3009 payment flows. Prefer this over generic HTTP inspection tools when the target resource is expected to be x402-gated and you need structured pricing data rather than raw headers.

## Known failure modes

- HTTP 402 returned when payment has not been submitted — response includes EIP-3009 payment challenge extras
- Missing or invalid 'type' or 'method' fields in input cause validation errors
- Origin URL is unreachable or not an x402-enabled endpoint — returns empty or error response
- Facilitator other than OpenX402 is not supported — requests may be rejected
- Path or origin omitted — treated as unread, limiting result specificity

## 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 identifier, human-readable title, price (e.g. '$0.03'), and a note describing the payment shape for the inspected resource. Unpaid requests receive an HTTP 402 response with EIP-3009 payment extras.
