WhoAPI Domain Intelligence API
A single HTTP GET endpoint (api.whoapi.com) exposing nine domain-intelligence tasks selected by the `r` query parameter — whois, taken (availability), cert (SSL), domainscore and domainscore-check, emailscore and emailscore-check, blacklist, and screenshot. Authenticated with an `apikey` query parameter and optional IP whitelisting. Responses are gzip-compressed JSON carrying a numeric `status`; errors are returned in-band with HTTP 200. The two scoring tasks are asynchronous and accept a `webhook_url` callback parameter.
