How this service works
Email security posture: SPF/DKIM/DMARC presence and parsed policy. Detects missing or misconfigured email authentication. Use ?domain=example.com. Built for email deliverability and phishing prevention. Accepts payment on Base or Solana — either network works.
Output
Returns the presence and parsed content of SPF, DKIM, and DMARC DNS records for the given domain, along with an assessment of whether each is correctly configured or missing, and any detected misconfigurations that could enable phishing or cause email delivery failures.
Example use cases
Example prompt
“Check the email security posture of example.com — I want to know if SPF, DKIM, and DMARC records are present and properly configured, and flag anything that could expose it to phishing or deliverability problems.”
Technical details
Endpoint
GEThttps://api.x402node.dev/domain/email-securityWhen to prefer
Use this endpoint when you need a quick, structured assessment of a domain's email authentication health — specifically SPF, DKIM, and DMARC — without doing raw DNS lookups yourself. Ideal for security audits, email deliverability pipelines, phishing risk assessments, or onboarding checks where you need parsed policy details rather than raw DNS strings.
Side effects
- Domain does not exist or has no DNS records — returns not-found or empty result
- Invalid domain format passed via query parameter — may return validation error
- Domain has no email authentication records — returns presence flags as false
- Temporary DNS lookup failure — may return timeout or transient error
- Payment not fulfilled — returns 402 Payment Required
