How this service works
Jobs from company ATS boards, SEC EDGAR full-text search, domain RDAP/DNS, NHTSA VIN decode + recalls, the CMS NPI Registry and MET Norway weather forecasts. Pay per call in USDC on Solana via x402. Official public sources only.
Output
Returns RDAP registration data for each queried domain including registrar name, registrant info, nameservers, domain status flags, creation and expiry dates, and optionally DNS records (A, MX, NS, etc.) when the dns=true flag is set. Up to 50 domains can be queried in a single call.
Example use cases
Domain ownership verification for due diligence
“I'm evaluating a potential acquisition — can you pull the RDAP registration details for acmecorp.com so I can see who owns it, the registrar, and when it expires?”
Bulk domain monitoring for brand protection
“Check the RDAP data for these domains: nikestore.com, nikeshoes.net, and nikeshop.co — I want to know who registered them and their current status.”
DNS record audit for IT security review
“Pull the DNS records for example-startup.io — I need to see the nameservers and any DNS entries as part of a security review.”
Technical details
Endpoint
GEThttps://x402-data-api-x6da.onrender.com/v1/domains?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative RDAP registration data and/or DNS records from official public sources for up to 50 domains in a single call, paid per-use via USDC on Solana. Prefer this over scraping WHOIS pages or calling registrar APIs directly, especially when you need structured machine-readable registration data without managing API keys for multiple registries.
Side effects
- Domain not found in RDAP registry — returns empty or 404-style record
- Invalid domain format causes validation error
- More than 50 domains provided — request rejected
- RDAP registry rate limiting or upstream unavailability
- DNS resolution failure for domains with no public DNS entries
- Payment not fulfilled — x402 payment required before data is returned
