How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the domain's RDAP handle, array of current statuses (e.g. 'active'), registrar name, registration date, and expiration date, plus the tool name identifier.
Example use cases
Domain expiry check before acquisition
“Look up the RDAP record for openai.com — I want to know when it expires and whether it's still active so I can decide if it's worth watching.”
Verify domain registrar for security audit
“Can you pull the RDAP info for paypal.com? I need to confirm which registrar holds it and see its current statuses for a security audit.”
Research competitor domain registration age
“Fetch the RDAP details for notion.so — I'd like to know when it was first registered and what its handle is.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/rdap-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable RDAP data about a domain's registration status, registrar, and key dates — especially in agent workflows that require pay-per-call pricing with no signup, verifiable delivery, and USDC payment via x402. Prefer over traditional WHOIS when you need JSON-structured output rather than raw text.
Side effects
- Domain not found in RDAP registry — returns empty or error result
- Timeout exceeded if registry responds slowly — configurable 1–15 second timeout
- Invalid domain format — malformed input may cause a validation error
- TLD not supported by RDAP — some legacy TLDs may lack RDAP coverage
- Network error reaching upstream RDAP registry — transient failure
