How this service works
146 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
A JSON object containing the domain name, a boolean indicating if it is registered, the registrar name, ISO 8601 creation and expiry timestamps, an array of nameserver hostnames, and an array of domain status codes (e.g. 'client delete prohibited').
Example use cases
Domain expiry monitoring for portfolio
“Check when stripe.com expires and who the registrar is — I want to make sure I track domains that might be dropping soon.”
Verifying a vendor's domain legitimacy
“Look up the registration details for acme-invoices.com — I want to see when it was registered and whether it looks legitimate before I pay an invoice from them.”
Research competitor infrastructure
“Pull the WHOIS data for shopify.com — I need the nameservers, registrar, and creation date for a competitive infrastructure analysis.”
Technical details
Endpoint
GEThttps://fastx402.tools/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured WHOIS/registration data (registrar, dates, nameservers, status) for a domain without setting up an account or API key — ideal for pay-as-you-go agent workflows querying one domain at a time via x402 micropayments on Base.
Side effects
- Domain not found or unregistered — registered field will be false with minimal data returned
- Invalid domain format — may return an error if the input is not a valid registrable domain
- WHOIS rate limiting or registry unavailability — upstream WHOIS services may be temporarily unreachable
- Internationalised domain names (IDN) may behave inconsistently depending on registry support
- Payment failure via x402 — request is not processed if USDC payment on Base cannot be settled
