How this service works
SPF policy lookup for Vendor screening: 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 DNS record for the specified domain along with a parsed breakdown of the SPF policy directives (e.g. include mechanisms, all qualifier, ip4/ip6 ranges). No email is sent and no inbox is verified — purely DNS data.
Example use cases
Third-party vendor email security audit
“We're onboarding a new SaaS vendor at stripe.com — can you fetch their SPF DNS record so I can review their email authorization policy before we approve them?”
Supplier due diligence screening
“I need to check the SPF configuration for supplierco.net as part of our procurement security checklist — look up their SPF TXT record and tell me what it says.”
Phishing risk assessment for partner domain
“Can you look up the SPF policy for globalpartners.io? I want to know if their domain is properly locked down to reduce phishing risk from spoofed emails.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/demand-domain-spf-policy-vendor-screening?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap DNS-only SPF policy lookup as part of a vendor screening or email security audit workflow. It is ideal for automated due diligence pipelines where you need to programmatically retrieve and parse SPF records without sending any email or verifying inboxes. Prefer this over full email deliverability or DMARC tools when SPF-specific DNS data is the only requirement.
Side effects
- Domain has no SPF TXT record — returns empty or indicates no SPF found
- Invalid or malformed domain input — returns an error indicating bad input
- DNS resolution failure — network or timeout error when querying DNS
- Domain does not exist — NXDOMAIN response from DNS
- Multiple SPF records found — ambiguous result as RFC 7208 disallows more than one SPF record
