How this service works
RDAP domain registration lookup: structured registrar, creation/updated/expiry dates, status, nameservers and a computed domain age. A parsed, snake_case JSON alternative to raw WHOIS text.
Output
A structured snake_case JSON object containing registrar name, creation/updated/expiry dates, domain registration status flags, nameservers list, and a computed domain age — a parsed alternative to raw WHOIS text.
Example use cases
Example prompt
“Can you look up the RDAP registration details for stripe.com — I want to see the registrar, when it was created and when it expires, its current status, and how old the domain is?”
Technical details
Endpoint
GEThttps://dns.use.x402atlas.com/rdapWhen to prefer
Prefer this endpoint over raw WHOIS lookups when you need structured, machine-readable domain registration data in snake_case JSON with a computed domain age field. It is ideal for automated pipelines, domain validation flows, or fraud/risk checks where parsing raw WHOIS text would be unreliable. Choose this over the sibling WHOIS endpoint when clean, normalized field names are required.
Side effects
- Domain not found or unregistered — returns empty or error response
- Domain TLD not supported by RDAP protocol
- Invalid domain format in query parameter
- Rate limit exceeded on repeated lookups
- RDAP upstream registry timeout or unavailability
