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 the domain's TLD, registration status, registrar name and IANA ID, creation and expiry dates, DNS MX records with priorities, nameservers, SPF and DMARC presence and policies, email provider name, and DNS status.
Example use cases
Email deliverability pre-flight check
“Before we send our outreach campaign to leads at acme.com, can you check whether they have DMARC with a reject policy and what their email provider is? I want to know if our emails are likely to land in inbox.”
Vendor domain health verification
“We're onboarding a new supplier at vendor-corp.io — can you check if their domain is properly registered, who the registrar is, and whether they have SPF set up? I want to make sure they're a legitimate operation.”
Company tech stack research
“I'm researching competitors in our space — can you look up the domain details for hubspot.com and tell me what email provider they run on and whether their DMARC is configured strictly?”

Endpoint
GEThttps://ats-jobs-api.groundtruthtools.workers.dev/x402/v1/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative DNS and registrar metadata for a specific company domain — particularly email provider detection, SPF/DMARC policy validation, or domain registration status checks. It is part of the ATS Jobs API platform which specializes in company-level data, making it well-suited for enriching company records alongside job posting data. Prefer it over generic WHOIS tools when you need structured, machine-readable output with parsed email provider identification.
Side effects
- Unregistered or non-existent domain returns registered: false with limited data
- Domain with no public RDAP/WHOIS data may return null for registrar and dates
- DNS timeout or lookup failure returns dns_status other than 'ok'
- Missing or malformed domain query parameter results in a 4xx error
- Some ccTLDs may have incomplete RDAP coverage yielding partial results
