Example prompt: Can you check if 'myawesomestartup.com' is available to register?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call domain availability check without committing to a full registrar account. Suitable for agents that need to programmatically verify domain status as part of a broader workflow, such as suggesting brand names or checking startup name availability.

## Known failure modes

- Invalid or malformed domain name input returns an error
- Domain TLD not supported returns an unsupported error
- Payment failure via x402 protocol blocks the request
- Rate limiting or timeout from upstream WHOIS/registrar service
- Network errors from the Vercel-hosted endpoint
