*
* - `url`: Request URL Same as the `$url` parameter to
* {@see \WpOrg\Requests\Requests::request()}
* (string, required)
* - `headers`: Associative array of header fields. Same as the `$headers`
* parameter to {@see \WpOrg\Requests\Requests::request()}
* (array, default: `array()`)
* - `data`: Associative array of data fields or a string. Same as the
* `$data` parameter to {@see \WpOrg\Requests\Requests::request()}
* (array|string, default: `array()`)
* - `type`: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the `$type`

* (string, default: `\WpOrg\Requests\Requests::GET`)
* - `cookies`: Associative array of cookie name to value, or cookie jar.
* (array|\WpOrg\Requests\Cookie\Jar)
*
* If the `$options` parameter is specified, individual requests will
* inherit options from it. This can be used to use a single hooking system,
* or set all the types to `\WpOrg\Requests\Requests::POST`, for example.
*
* In addition, the `$options` parameter takes the following global options:
*
* - `complete`: A callback for when a request is complete. Takes two
* parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the
* ID from the request array (Note: this can also be overridden on a
