## 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 live-subdomain-enumeration-for-mpp-api-agentmail-to-e1dfb6dc
```

Example prompt: Can you run a passive subdomain enumeration on mpp.api.agentmail.to and show me what subdomains are publicly discoverable, along with any risk factors or confidence score?

## When to prefer this

Use this endpoint when you need a pre-scoped, ready-to-call passive subdomain enumeration specifically for mpp.api.agentmail.to without configuring your own subfinder toolchain. It is ideal for quick security audits, pre-integration reconnaissance, or attack surface assessments of the agentmail mail service infrastructure at a fixed low cost per call.

## Known failure modes

- Payment not settled — endpoint returns 402 if x402 payment is not completed
- Domain not found or no subdomains discovered — result may return empty evidence
- Network timeout or subfinder upstream failure — ok:false in result
- Invalid query parameter values — schema validation error
- Free metadata call (meta=1) returns only metadata JSON, not subdomain results

## How this service works

Probe-grounded live composite (Short response; subdomain enumeration maps mail service attack surface.): Passive subdomain enumeration for a domain via public sources (subfinder). Live check for mpp.api.agentmail.to.

## Output

Returns a JSON object with ok/paid status, a service slug, a score, a natural-language summary, an evidence object, lists of strengths and risk factors, a confidence level, and a generatedAt ISO-8601 timestamp — all describing the subdomain landscape of mpp.api.agentmail.to.
