Example prompt: Can you check whether the SPF record for acmecorp.com authorizes Greenhouse to send email on its behalf, and show me the matching mechanism and the full SPF record?

## When to prefer this

Use this endpoint when you need to specifically verify whether Greenhouse (the recruiting/ATS platform) is authorized in a domain's SPF record. It is more precise than a generic SPF lookup because it targets Greenhouse's specific include and IP mechanisms. Prefer this over manual DNS inspection or general SPF tools when automating deliverability audits or vendor integration checks for Greenhouse.

## Known failure modes

- Domain has no SPF TXT record — returns no authorization with empty record
- Domain does not exist or DNS lookup fails — returns an error
- SPF record exists but contains no Greenhouse-related mechanisms — returns no with the full record
- Malformed SPF record that cannot be parsed — may return error or inconclusive result

## How this service works

Does the domain's SPF record authorise greenhouse to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for greenhouse's include/ip mechanisms, returning yes/no, the matching mechanism and the full record. Confirms a vendor integration is wired for deliverability, or spots an unexpected sender. $0.01 per lookup.

## Output

Returns a yes/no indicating whether Greenhouse is authorized by the domain's SPF record, the specific SPF mechanism that matched (e.g. an include: or ip4: entry), and the complete SPF TXT record retrieved via Cloudflare DoH.
