Looks up DNS MX records and email configuration evidence for a given email address's domain, returning observed DNS data with source provenance.

## 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 foundry-email-domain-evidence-e01ef53c -d '<json body>'
```

Example prompt: Can you check the MX DNS records for the domain in john.doe@acmecorp.io and tell me whether it's configured to receive email, with source evidence?

## When to prefer this

Choose this endpoint when you need verifiable, sourced DNS MX evidence for an email domain — not just a syntax check. It is ideal for compliance logging, fraud detection, onboarding validation, or any workflow requiring documented proof of DNS configuration with source attribution. Prefer it over generic email validators when you need structured JSON evidence with source provenance and DNSSEC status, and when you need an auditable record of what the DNS showed at a specific point in time.

## Known failure modes

- Invalid or malformed email address returns syntax error or INVALID_SYNTAX status
- Domain with no MX records returns NO_DATA status with empty records array
- DNSSEC status may be UNKNOWN if not resolvable
- Mailbox existence is always UNKNOWN — no mailbox-level verification is performed
- DNS lookup may time out for slow or unreachable authoritative nameservers
- Payment failure (HTTP 402) if USDC balance insufficient

## How this service works

Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.

## Output

Returns a JSON object containing: observed MX DNS records (name, type, RCODE, DNSSEC status, source URL, record status, raw records, observation timestamp, and attribution to Cloudflare 1.1.1.1), the normalized domain, a syntax validity status for the input email, a mail domain verdict (e.g. UNKNOWN, VALID, INVALID), a mailbox existence indicator, observation timestamp, and any limitations notes.
