How this service works
Curated x402 website intelligence API for autonomous AI agents. 24 high-value paid tools covering web content, company research, ecommerce product intelligence, SEO, security and domain trust.
Output
Returns a JSON object with boolean fields indicating whether the target domain has MX records (mail server configured), SPF records (sender policy framework), and DMARC records (domain-based message authentication) present — e.g. {"mx": true, "spf": true, "dmarc": false}.
Example use cases
Vendor email security due diligence
“Before we start emailing invoices to our new vendor at acmecorp.com, can you check if their domain has MX, SPF, and DMARC records configured so I know our emails will actually reach them?”
Phishing risk assessment for a domain
“I got an email claiming to be from payments.globalbank.com — can you check if that domain has proper DMARC and SPF records set up so I can judge whether it's likely to be legitimate or spoofed?”
Email readiness audit before outreach campaign
“We're about to launch a cold outreach campaign to leads at startupxyz.io — can you verify that their domain has MX, SPF, and DMARC configured so we're not sending into a black hole?”
Technical details
Endpoint
POSThttps://elon.tail49499f.ts.net/domain/email-securityWhen to prefer
Use this endpoint when you need a quick, low-cost check of a domain's email security posture — specifically MX, SPF, and DMARC record presence — without needing full DNS record dumps or deliverability scoring. Ideal for pre-outreach validation, vendor due diligence, or phishing risk assessments where you just need boolean pass/fail signals on the three core email authentication pillars.
Side effects
- Invalid or malformed URL input returns an error
- Domain does not exist or is unreachable, resulting in all false or an error response
- DNS lookup timeouts for slow or unresponsive nameservers
- Private or localhost URLs may be rejected
- Rate limiting if too many requests are made in rapid succession
