## 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 agent-vending-domain-intelligence-a7621ae7 -d '<json body>'
```

Example prompt: Can you pull a full domain intelligence report for stripe.com — DNS records, SPF and DMARC mail posture, and overall domain health?

## When to prefer this

Choose this endpoint when you need a comprehensive, multi-signal domain profile in a single call — combining DNS records, email security posture (SPF/DMARC), a homepage excerpt, and health heuristics. It is ideal for pre-outreach domain vetting, vendor due diligence, or competitive research where you want structured intelligence rather than raw DNS queries or email-address-level validation. Prefer it over a standalone email validator when the target entity is a domain rather than a specific address.

## Known failure modes

- Private, loopback, or local domain targets are rejected with a validation error
- Domain not found or DNS resolution failure returns an empty or partial record set
- Homepage fetch may fail for domains with bot-blocking or non-standard HTTP configurations
- DMARC/SPF fields may be absent if the domain has not configured them
- Transient DNS resolution timeouts may cause partial results

## How this service works

Pay-per-call machine utilities for autonomous agents.

## Output

A structured JSON intelligence pack containing: DNS records (A, AAAA, MX, NS, TXT), parsed SPF and DMARC mail posture, a markdown excerpt of the domain's homepage, and a heuristic domain health assessment. All data is derived from public lookups only.
