How this service works
Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.
Output
A JSON object containing domain metadata including: TLD, registration status, registrar name and IANA ID, creation and expiry dates, DNS status, nameservers, MX records, SPF presence and policy, DMARC presence and policy, email provider, and the registration data basis (e.g. RDAP).
Example use cases
Verify company email security posture
“Check stripe.com's domain and tell me if they have SPF and DMARC configured, and what their DMARC policy is — I need to know if they're protected against email spoofing.”
Research company infrastructure before outreach
“Before I send emails to people at acme.com, can you look up their domain and tell me what email provider they use and whether the domain is properly registered and active?”
Due diligence on a vendor domain
“I'm vetting a vendor at openai.com — can you pull their domain registration details including registrar, creation date, expiry date, and nameservers so I can check everything looks legitimate?”
Technical details
Endpoint
GEThttps://companyfacts.dev/x402/v1/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable domain health and registration data for a specific company domain — especially when you need registrar details, email provider identification, and email security (SPF/DMARC) configuration in a single call. Prefer this over manual WHOIS lookups or generic DNS tools when you need parsed, normalized output ready for downstream logic.
Side effects
- Domain not found or unregistered — registration status will be false
- Invalid domain format passed — may return error or empty result
- RDAP/WHOIS lookup timeout for certain TLDs
- SPF or DMARC fields may be null if not configured by domain owner
- Expiry or creation dates may be absent for some registrars
