How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing a list of parsed SPF mechanisms (e.g. include: directives, ip4/ip6 ranges, terminal directive), the terminal policy string (e.g. '-all', '~all'), and a count of DNS lookup terms used. Also includes schema version, operation name, and evidence metadata (input SHA256, retained=false, external_calls count).
Example use cases
Audit email sender configuration
“I need to understand what's in this SPF record — can you break it down into its mechanisms and tell me how many DNS lookups it uses? Here it is: 'v=spf1 include:_spf.google.com include:mailgun.org ip4:203.0.113.5 ~all'”
Check SPF lookup limit compliance
“Can you parse this SPF record and count the DNS lookup terms? I want to know if we're at risk of hitting the 10-lookup limit: 'v=spf1 include:_spf.example.com include:sendgrid.net include:mailchimp.com include:amazonses.com -all'”
Extract SPF terminal policy
“What's the terminal directive in this SPF record — is it a hard fail, soft fail, or neutral? Record is: 'v=spf1 ip4:10.0.0.0/8 include:_spf.example.com ?all'”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/dns-spf-record-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, in-memory, no-retention parsing of a raw SPF record string into structured data. It is ideal for agents performing email infrastructure audits, validating SPF syntax, or counting DNS lookup terms without needing to do a live DNS query. At $0.001 per call with no signup, it suits high-frequency automated checks. Prefer it over general-purpose parsing libraries when you need a verified, schema-versioned result with an input hash for auditability.
Side effects
- Malformed or empty SPF record string may return a parse error or unexpected mechanism list
- Records exceeding 8192 characters will be rejected by input validation
- Non-SPF TXT records passed as input may produce empty or nonsensical mechanism lists
- Records with circular include chains cannot be fully resolved at parse time (only the literal string is parsed)
