## 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 knight-logics-agent-discovery-audit-a19cfea8 -d '<json body>'
```

Example prompt: Can you run an agent discovery audit on https://agent.myservice.com and tell me whether it's ready, what checks passed or failed, and what's blocking discoverability?

## When to prefer this

Choose this endpoint when you need a structured, scored, per-check audit of an agent's A2A discoverability and agent-card compliance — especially when you want machine-readable results with evidence hashes for logging or CI pipelines. Prefer it over manual inspection when you need a definitive 'ready' or 'not ready' decision with specific blocker details.

## Known failure modes

- Target URL is unreachable or returns non-2xx — checks will fail and blockers will be listed
- Agent card JSON is malformed or missing required fields — check passes HTTP but fails content validation
- Origin does not serve a /.well-known/agent-card.json path — agent card check fails
- Rate limit or payment failure for the $0.10 USDC x402 call — request rejected before audit runs
- Invalid or malformed input URL — API returns error before any checks are performed

## How this service works

Public website contact extractor for CRM enrichment: emails, phones, forms, socials, DNS mail-policy. Also on Apify ($0.005/site) and RapidAPI (BASIC free).

## Output

Returns a JSON object with a numeric readiness score (0–100), an array of individual check results (each with URL, check name, pass/fail status, HTTP status, content type, byte count, and SHA-256 hash of evidence), the audited origin, a list of blockers preventing readiness, an overall decision string (e.g. 'ready'), a generation timestamp, and a top-level evidence SHA-256 hash.
