Fingerprint the DNS provider serving a domain from its public NS records. Returns the record name written the way that provider's form expects it (@ vs blank vs the full domain), whether it can point a zone apex, where its record editor lives, and the provider-specific settings that silently break custom domain setups.

Free. No API key required. CORS-enabled. Rate-limited per IP at 30/min and 500/day.

Parameters

Name	In	Type	Description
`domain`required	query	`string`	Domain or hostname. Subdomains are walked up to the zone that holds the NS records. example: `example.com`
