How this service works
DNS SPF Record Parse: DNS SPF Record Parse parses SPF version, mechanisms, modifiers, and terminal policy from bounded caller-supplied values without an external provider. Call DNS SPF Record Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS SPF Record Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, mem…
Output
Returns versioned deterministic JSON containing the parsed SPF version, a list of mechanisms (e.g. include, ip4, ip6, a, mx), modifiers (e.g. redirect, exp), the terminal policy (all qualifier: +, -, ~, ?), and an explicit pass or advisory status reflecting the validity of the record.
Example use cases
Email deliverability audit
“I have this SPF record from our domain and I need to know every mechanism and modifier in it, plus what the final policy is — can you break it apart: 'v=spf1 include:mailgun.org ip4:203.0.113.5 ~all'?”
Security review of SPF policy
“Before we accept mail from this sender, can you parse their SPF record and confirm whether it has a hard-fail or soft-fail terminal policy? The record is: 'v=spf1 include:_spf.example.com -all'.”
Debugging SPF configuration
“Something is wrong with our email setup — can you parse this SPF TXT record and show me all the mechanisms in structured form so I can figure out what's missing: 'v=spf1 include:spf.protection.outlook.com ip6:2001:db8::/32 ?all'?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/dns-spf-record-parseWhen to prefer
Use this endpoint when you need to deterministically parse and normalize an SPF DNS record string into structured components without any external DNS lookup or third-party dependency. It is ideal for pipelines that need to inspect SPF policy before caching, redirecting, or accepting email, and where stateless, reproducible parsing is required. Prefer this over general-purpose DNS lookup tools when the raw SPF record text is already known and only structural decomposition is needed.
Side effects
- Record string exceeds 8192 character limit — returns validation error
- Malformed or non-SPF string provided — may return parse error or advisory fail status
- Empty record field — missing required input error
- Non-SPF DNS record passed (e.g. DKIM or DMARC) — may parse but return unexpected or empty fields
