How this service works
Metered web utilities for developers and AI agents: browser screenshot and PDF, crypto, DNS and net tools. Pay per request with x402 (USDC on Base) or prepaid API keys.
Output
Returns a JSON object with ok status, the utility name, a request ID, credits charged, and the full RDAP response for the queried domain, IP, or ASN — including registrant details, registration/expiry dates, registrar information, nameservers, and status flags.
Example use cases
Domain ownership investigation
“I need to find out who owns suspicious-site.xyz — can you do an RDAP lookup and tell me the registrant, registrar, and when it was created?”
IP address registration check
“Run an RDAP lookup on the IP address 203.0.113.42 and tell me which organization it's registered to and the associated ASN.”
Domain expiry monitoring
“Check RDAP for mycompetitor.com and tell me when their domain registration expires so I know if they might be letting it lapse.”
Technical details
Endpoint
POSThttps://util.beauty/v1/net/rdapWhen to prefer
Choose this endpoint when you need structured, machine-readable domain or IP registration data (RDAP) without setting up your own DNS/RDAP client. Ideal for AI agents that need to resolve ownership or registration metadata on-demand, paying only per request via x402 USDC micropayments. Prefer over raw WHOIS when you need JSON-structured output and consistent formatting across registries.
Side effects
- Domain or IP not found in RDAP registry — returns error or empty result
- Invalid input format (malformed domain or IP) — returns validation error
- RDAP registry timeout or unavailability — returns upstream error
- Insufficient credits or payment failure — returns 402 Payment Required
- Rate limiting if too many requests in a short window
