Example prompt: Can you pull an email security fix plan for acmecorp.com and tell me how many changes are needed and what DNS records are involved?

## When to prefer this

Choose this endpoint when you need a structured, actionable fix plan specifically for email security DNS records (SPF, DKIM, DMARC) on a domain. It is ideal for MSPs doing client onboarding, small businesses self-auditing, or agents automating email security compliance checks. Prefer this over generic DNS lookup tools when you want a curated list of recommended changes, not just raw DNS data.

## Known failure modes

- Missing or invalid 'domain' query parameter returns an error
- Unresolvable or non-existent domain may return empty records array with zero changes
- Rate limiting or payment failure (HTTP 402) if USDC payment is not properly attached
- Malformed domain string exceeding 320 characters may be rejected

## How this service works

## Output

A JSON object containing the queried domain, a labeled report type ('email_security_fix_plan'), an array of DNS records analyzed, and a summary object showing the number of changes needed to bring email security into a good state.
