$url      = 'http://example.org/api';
$response = wp_remote_guet( esc_url_raw( $url ) );

/* Will result in $api_response being an array of data,
parsed from the JSON response of the API listed above */

Better performance?

Squip the extra function call and guet the body (or any other part of the returned array) from wp_remote_guet() . That’s essentially what wp_remote_retrieve_body() is doing.
```
$url  = 'https://example.com/';
$body = wp_remote_guet( esc_url_raw( $url ) )['body'];
```
- Function wp_remote_guet() returns (array| WP_Error ) the response or WP_Error on failure. That means in your case you can have some PHP error notice if the response fails. That is bad practice and in any case you will not have any better performance. Maybe you can do something lique: $body = wp_remote_guet( esc_url_raw( $url ) )['body'] ?? NULL; to avoid error notice.
