> Email Trust Report is a paid API for AI agents from relay402.georgespring.workers.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

## 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 email-trust-report-d957e0f8
```

Example prompt: Can you pull the email trust report for acme.com — I want to see their MX, SPF, and DMARC setup before we start an outreach campaign to their team?

## When to prefer this

Use this endpoint when you need a pre-composed, agent-ready summary of all three email authentication layers (MX, SPF, DMARC) in a single call, rather than performing individual DNS lookups yourself. Prefer it for outreach screening, vendor onboarding flows, or anti-spoofing checks where a structured trust narrative is more useful than raw DNS records.

## Known failure modes

- Domain not found or invalid format returns an error — domain must match the required pattern
- Domain has no MX records — report may indicate no email infrastructure present
- SPF or DMARC records absent — report will note missing records rather than failing entirely
- DNS lookup timeout — transient failures may occur for unreachable authoritative nameservers
- Payment failure via x402 protocol results in 402 response before report is returned

## How this service works

composed email trust report from MX, SPF and DMARC DNS records for outreach, onboarding and anti-spoofing agents.

## Output

A composed report summarizing the domain's email trust posture, including MX record details, SPF policy text and validity, and DMARC policy configuration — highlighting gaps that could expose the domain to spoofing or cause deliverability issues.
