## 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 blackhull-x402-service-findings-report-f4063eb4
```

Example prompt: Can you pull the Blackhull findings report for this x402 service — https://www.ax1.vc/api/dashboard/q-verdict/resource — and tell me its grade and any issues flagged?

## When to prefer this

Choose this endpoint when you need a structured, graded risk report on a specific x402 service URL — including coded findings with evidence — rather than just a list of raw flags. Prefer this over the sibling 'flags' endpoint when you want severity levels, grade rollup, and evidence data bundled together. Best used before integrating or paying for an unfamiliar x402 API.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error
- URL not indexed or not recognized as an x402 resource may return no findings or an error
- Network timeout if the target resource is unreachable
- Stale data if the report snapshot date (2026-10-30) predates recent changes to the service

## How this service works

Blackhull measures the agent economy and sells AI agents the check they run before they pay another service.

## Output

A JSON object containing the queried URL, an overall grade (e.g. CAUTION, PASS, FAIL), and an array of findings each with a code (e.g. CONCENTRATED_DEMAND), severity level, and structured evidence data such as payment counts, observation windows, and top-wallet share percentages.
