Registration data for any domain, straight from authoritative RDAP registries (the structured WHOIS successor): registrar, ICANN/EPP domain status codes, creation, last-updated and expiration dates, authoritative nameservers, and DNSSEC delegation. The fast, license-clean way for an agent to vet a domain, sender, or counterparty. Keyless, structured JSON, pay-per-call.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
