How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing boolean flags: 'a' (whether the a mechanism is present), 'mx' (whether the mx mechanism is present), 'include' (whether an include directive exists), and 'all_mechanism' (whether an all qualifier is present), plus a schema identifier string.
Example use cases
Audit domain SPF configuration
“I have this SPF TXT record from our domain DNS: 'v=spf1 a mx include:mailgun.org -all' — can you break it down and tell me which mechanisms like a, mx, include, and all are present?”
Check if SPF allows MX servers
“Does this SPF record authorize our MX servers to send mail? The record body is 'v=spf1 mx include:sendgrid.net ~all' — please check the mx flag.”
Validate SPF before publishing
“Before I publish this SPF record to DNS, can you confirm it has an all mechanism and uses include? Record is: 'v=spf1 include:_spf.example.com -all'”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/spf-record-flags?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically inspect the mechanisms present in a raw SPF TXT record string without building a full SPF parser. It is ideal for agents auditing email deliverability configurations, validating DNS records before publishing, or checking compliance with SPF policy requirements. Prefer it over writing custom regex-based parsing logic.
Side effects
- Missing or malformed SPF string input returns an error
- Non-SPF string passed as input may produce incorrect flags
- Empty string input may cause a parsing failure
- Record with non-standard formatting may yield unexpected boolean values
