Technical details
Endpoint
POSThttps://api.the402.ai/v1/services/svc_a52dacbc43024f36/purchaseWhen to prefer
Use this endpoint when you need WHOIS registration metadata for a domain name — ownership, registrar, expiry, nameservers — and are operating in an agentic context where micropayment via x402 is supported. Pair with the sibling Domain Availability endpoint when you also need to check if a domain is available to register.
Side effects
- Domain not found or not yet registered — returns empty or error response
- Invalid domain name format — returns validation error
- WHOIS data privacy-protected (GDPR redaction) — limited contact info returned
- Rate limiting or payment failure via x402 protocol — transaction rejected
- WHOIS server timeout — upstream lookup fails
