How this service works
50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.
Output
A JSON object containing SPF presence status, DMARC policy (e.g. 'reject', 'quarantine', 'none'), and a list of detected email security issues (empty array if none found).
Example use cases
Vendor domain security screening
“Before we send invoices from our partner acme-corp.com, can you check whether they have proper SPF and DMARC records in place and flag any email security issues?”
Pre-send phishing risk check
“I'm about to run an email campaign from newstartup.io — can you verify that the domain has SPF and DMARC set up correctly so our emails won't be spoofed or rejected?”
Security audit for client domain
“My client uses support.globalretail.net for transactional emails — can you audit its email security configuration and tell me if the DMARC policy is set to reject and if there are any SPF problems?”
Technical details
Endpoint
GEThttps://skinwinking.com/api/v1/web/email-security?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call check of a domain's email security posture (SPF/DMARC) without setting up your own DNS tooling. It is especially useful in agent workflows that screen vendor or partner domains, audit client infrastructure, or validate outbound email configuration before campaigns. At $0.002 per call it is cost-effective for one-off or low-volume domain checks.
Side effects
- Invalid or non-existent domain returns an error or empty result
- Domain with no DNS records may return all fields as absent or false
- Network/DNS lookup timeout may result in a generic error response
- Malformed domain input (e.g. including protocol prefix) may cause a validation error
