Example prompt: Can you look up the SPF DNS policy for github.com and tell me what mail servers are authorized to send email on its behalf?

## When to prefer this

Choose this endpoint when you need to inspect or validate a domain's SPF policy for IT administration, email security auditing, or deliverability debugging. It is DNS-only and read-only — ideal when you want a lightweight, side-effect-free SPF lookup without sending any email or verifying inbox existence. Prefer this over broader email validation services when only the SPF record is needed.

## Known failure modes

- Domain has no SPF TXT record — returns empty or not-found result
- Invalid or non-existent domain — DNS resolution fails
- Domain has multiple TXT records causing SPF ambiguity
- Network or DNS timeout when resolving the record
- Malformed SPF record that cannot be parsed

## How this service works

SPF policy lookup for IT administration: Return and parse the domain SPF TXT policy. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the raw SPF TXT record string for the domain along with a parsed breakdown of its mechanisms (e.g. include, ip4, ip6, a, mx, all) and qualifiers, showing which mail servers are authorized to send on behalf of the domain. DNS data only — no email sending or inbox verification.
