The command you provided is an HTTP request that makes use of the http command-line tool. It is making an HTTP DELETE request to the URL ${https:--example-com-todos-7} with an additional header API-Key: foo.

Let's break down the command:

• http is a command-line tool commonly used to make HTTP requests.
• DELETE is the HTTP method being used in this request. It indicates that the client wants to delete a resource at the given URL.
• ${https:--example-com-todos-7} is a placeholder for the actual URL. The URL needs to be properly formatted and should be substituted in place of this placeholder. For example, if the intended URL is https://example.com/todos/7, it should be used instead.
• ${API-Key:foo} is an additional header being sent in the request. It specifies the value of the API-Key header as foo. This header can be used for authentication or authorization purposes.

To successfully execute this command, replace the placeholders with their appropriate values and use a tool like httpie or curl to send the request.
