How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
Returns a JSON object with structured RDAP data for the queried domain, including registrar name, registration and expiry dates, domain status flags, nameserver list, and optionally registrant contact details where publicly available. The response indicates success with an 'ok' flag.
Example use cases
Domain ownership investigation
“Who owns the domain stripe.com? I want to see the registrar, registrant org, and registration dates from the official RDAP record.”
Competitor domain monitoring
“Pull the RDAP registration data for my competitor's domain, acmecorp.io — I want to know when it was registered and when it's due to expire.”
Due diligence before acquisition
“I'm considering buying the domain vintagetrucks.com — can you fetch its RDAP record so I can see the current status, registrar, and expiry date before I make an offer?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/rdap_domain_lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, machine-readable domain registration data in RDAP format rather than raw WHOIS text. Prefer it over WHOIS scraping for reliable, standardized JSON output. Best for due diligence, domain monitoring, ownership investigation, or any workflow that needs authoritative registration metadata per call at low cost with no API key setup.
Side effects
- Domain not found or unregistered — RDAP may return empty or error response
- Invalid domain name format — validation failure before lookup
- RDAP registry timeout — upstream registry may be slow or unreachable
- TLD not covered by RDAP — some ccTLDs may not have RDAP endpoints
- Rate limiting from upstream RDAP registry
