Example prompt: Can you do a full DNS email security audit on stripe.com — check their MX, SPF, DMARC, DKIM, BIMI, and MTA-STS records and tell me what's missing or misconfigured?

## When to prefer this

Use this endpoint when you need a comprehensive, all-in-one audit of a domain's email authentication stack (MX, SPF, DMARC, DKIM, BIMI, MTA-STS, TLS-RPT) in a single call, rather than querying individual DNS record types manually. Especially useful for security assessments, onboarding checks, or diagnosing email deliverability issues.

## Known failure modes

- Domain not found or unresolvable — returns error indicating DNS lookup failure
- Malformed domain input — returns validation error
- Timeout on DNS resolution for a slow or non-responsive nameserver
- Partial results if some record types are inaccessible
- Payment not processed — returns 402 if x402 payment header is missing or insufficient

## Output

Returns a structured breakdown of the domain's email authentication and DNS security posture, covering the presence and validity of MX, SPF, DMARC, DKIM, BIMI, MTA-STS, and TLS reporting records, along with findings about misconfigurations or missing records.
