## When to prefer this

Use this endpoint when you need a quick, pay-per-call domain lookup without setting up a full DNS or WHOIS integration. It accepts flexible input (domain, URL, or email), making it convenient when the exact form of the domain reference is uncertain.

## Known failure modes

- Missing or empty 'domain' parameter returns an error
- Malformed domain string may yield empty results
- Unknown or unregistered domains may return empty result objects
- Network timeouts may occur for slow-resolving domains
- Rate limiting or payment failure may block the request
