# Agent Utility Suite – Domain Email & Web Profile

> Agent Utility Suite – Domain Email & Web Profile is a paid API for AI agents from x402-agent-api.onrender.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-12).

Profiles a domain's email infrastructure (MX, SPF, DMARC, email provider) and web presence (HTTPS, reachability, HTTP headers, domain verifications) in a single call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-utility-suite-domain-email-web-profile-5b00da9a -d '<json body>'
```

Example prompt: Can you profile stripe.com's email setup — I want to know what email provider they use, whether SPF and DMARC are configured, and if their site is reachable over HTTPS?

## When to prefer this

Use this endpoint when you need a combined snapshot of a domain's email infrastructure (MX, SPF, DMARC, email provider) and web presence in a single low-cost call. Prefer it over raw DNS lookup tools when you want structured, parsed results (e.g. email provider name, DMARC policy label, verification badges) without managing DNS queries yourself. Ideal for lead enrichment, vendor onboarding checks, competitive research, and email deliverability audits. Not suited for real-time monitoring or bulk crawling of thousands of domains.

## Known failure modes

- Domain does not exist or is unreachable — returns empty or null fields for website and DNS records
- Invalid domain format — returns validation error
- Domain has no MX records — has_mx_records: false, mx_hosts empty
- No SPF or DMARC configured — respective fields null or false
- Payment not completed — 402 response until x402 payment signature is provided
- Rate limiting or upstream DNS timeout — may return partial results or error

## How this service works

Answers 'Who hosts this company's email, and is it set up properly?' for lead enrichment, deliverability and vendor checks: MX records and email provider (Google Workspace, Microsoft 365, ...), SPF and DMARC policy, SaaS the domain has verified ownership with (Google, Microsoft, Stripe, Atlassian, ...), HTTPS reachability and security headers, from live DNS and the website. Not charged on invalid input or upstream failure. $0.004 USDC per call.

## Output

Returns a JSON object with the profiled domain, HTTP response headers, website reachability and HTTPS status, MX host list, SPF record string, DMARC policy, TXT records array, detected email provider (e.g. Google Workspace, Microsoft 365), domain ownership verification badges (e.g. Google, Atlassian, Facebook), and timestamp of the check.
