Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/domain-rdap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, structured domain registration metadata (RDAP protocol) rather than raw WHOIS text, especially when you need machine-readable expiry dates, registrar info, nameservers, or DNSSEC status for a specific domain. Prefer over WHOIS scraping tools when structured JSON output is required.
Side effects
- Domain not found or not yet registered — returns an error or empty record
- Invalid domain format supplied — returns a validation error
- RDAP registry unavailable for the TLD — returns a lookup failure
- Rate limiting or payment failure at $0.02 USDC — returns 402 or 429 error
