WhoAPI Domain Intelligence API is published by [WhoAPI](https://apis.io/providers/whoapi/) on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Domain Intelligence. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, and authentication docs.

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.
