How this service works
SPF lookup budget estimate for IT administration: Count common DNS lookup mechanisms in an SPF policy; this is a static estimate. DNS data only; does not send email or verify that an inbox exists.
Output
Returns a static count of DNS lookup-consuming mechanisms (such as include, a, mx, redirect, exists, ptr) found in the domain's SPF TXT record, providing an estimated total against the RFC 7208 limit of 10 permitted lookups.
Example use cases
Pre-deployment SPF policy audit
“We're about to add a new email vendor to our SPF record for techventures.io — can you check how many DNS lookups our current SPF policy already uses so I know if there's room?”
IT compliance SPF check
“I need to audit our SPF configuration for compliance — can you count how many DNS lookups are in the SPF record for mybusiness.com and tell me if we're at risk of exceeding the limit?”
Troubleshoot email delivery SPF errors
“We've been having email delivery issues and I suspect our SPF record for startupco.com might have too many lookups — can you count them and tell me the current budget estimate?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-spf-lookup-count-it-administration?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, static estimate of SPF DNS lookup consumption for a domain without sending any email or performing live DNS chain resolution. Ideal for IT admins auditing SPF policies before adding new include mechanisms, for compliance checks, or for diagnosing potential SPF permerror caused by exceeding the 10-lookup limit. Not suitable when you need a full recursive runtime lookup count or live inbox verification.
Side effects
- Domain has no SPF TXT record — returns zero or an error indicating no SPF policy found
- Domain does not exist or DNS resolution fails — returns an error
- SPF record is malformed or unparseable — may return partial or error response
- Nested includes beyond static analysis depth may undercount actual runtime lookups
