How this service works
Answers 'Who hosts this company's email, and is it set up properly?' for lead enrichment, deliverability and vendor checks: MX records and email provider (Google Workspace, Microsoft 365, ...), SPF and DMARC policy, SaaS the domain has verified ownership with (Google, Microsoft, Stripe, Atlassian, ...), HTTPS reachability and security headers, from live DNS and the website. Not charged on invalid input or upstream failure. $0.004 USDC per call.
Output
Returns a JSON object with the profiled domain, HTTP response headers, website reachability and HTTPS status, MX host list, SPF record string, DMARC policy, TXT records array, detected email provider (e.g. Google Workspace, Microsoft 365), domain ownership verification badges (e.g. Google, Atlassian, Facebook), and timestamp of the check.
Example use cases
Email provider identification for outreach
“Before I start a cold email campaign targeting acme.com, can you check what email provider they use and whether their domain has proper SPF and DMARC records set up?”
Competitor email security audit
“Can you audit the email security posture of openai.com — I want to know if they have SPF, DMARC, MX records, and what domain verifications they have in place?”
Vendor domain reachability check
“I need to verify that our new vendor's domain, widgets-corp.com, actually has a live website over HTTPS and a working email setup with MX records before we onboard them.”
Technical details
Endpoint
POSThttps://x402-agent-api.onrender.com/api/v1/domain-enrich?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a combined snapshot of a domain's email infrastructure (MX, SPF, DMARC, email provider) and web presence in a single low-cost call. Prefer it over raw DNS lookup tools when you want structured, parsed results (e.g. email provider name, DMARC policy label, verification badges) without managing DNS queries yourself. Ideal for lead enrichment, vendor onboarding checks, competitive research, and email deliverability audits. Not suited for real-time monitoring or bulk crawling of thousands of domains.
Side effects
- Domain does not exist or is unreachable — returns empty or null fields for website and DNS records
- Invalid domain format — returns validation error
- Domain has no MX records — has_mx_records: false, mx_hosts empty
- No SPF or DMARC configured — respective fields null or false
- Payment not completed — 402 response until x402 payment signature is provided
- Rate limiting or upstream DNS timeout — may return partial results or error
