## 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-integration-pack-lookup-83760aa8 -d '<json body>'
```

Example prompt: Before I integrate this x402 endpoint at https://example.hstgr.cloud/route/some-service, can you pull its full I/O schema, some example inputs and outputs, the price per call, and its probe-measured delivery grade so I don't have to risk a test purchase?

## When to prefer this

Use this endpoint when an agent or developer needs to safely inspect an x402-listed API's contract, pricing, and reliability before committing to a real paid call. It is specifically valuable in agentic pipelines where test purchases are risky or undesirable, and when working within the x402/bazaar ecosystem where machine-readable schema metadata is expected to be available. Prefer this over generic HTTP inspection tools when you need delivery-grade quality signals sourced from actual probe history.

## Known failure modes

- URL not found in bazaar or paid-response archive — returns empty or not-found response
- Endpoint URL is malformed or unreachable — validation error
- Probe data unavailable for a newly listed endpoint — delivery grade may be absent
- Schema not advertised by the listing — returns partial metadata only
- Network timeout contacting the archive — transient failure, no charge applied

## How this service works

POST {url} of any x402 listing -> its machine-readable I/O schema (from the advertised bazaar extension or our paid-response archive), input/output examples, price, and probe-measured delivery grade. Saves a coding agent a risky test purchase against an endpoint that may not deliver. Never charged on failure.

## Output

Returns the machine-readable I/O schema (input and output field definitions), concrete input/output examples, the per-call price, and a probe-measured delivery grade indicating how reliably the endpoint has fulfilled paid requests — all sourced from the bazaar extension metadata or a paid-response archive. No charge is incurred if the lookup fails.
