Example prompt: Can you check if 'coolstartup.io' 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 domain registrar API integration. Suitable for agents that need to validate domain names on demand as part of a larger workflow, such as brand research, business setup, or e-commerce tooling.

## Known failure modes

- Invalid domain format returns an error or empty result
- Network timeout from upstream WHOIS or registry lookup
- Domain TLD not supported by the checker
- Ambiguous or malformed input domain causes unexpected response
- API returns generic example response if domain parameter is missing
