/**
 * The Legacy REST API was removed in WooCommerce 9.0 and is now available as a dedicated extension.
 * A stub is kept in WooCommerce core that acts when the extension is not installed and has two purposes:
 *
 * 1. Return a "The WooCommerce API is disabled on this site" error for any request to the Legacy REST API endpoints.
 *
 * 2. Provide the not-endpoint related utility methods that were previously supplied by the WC_API class,
 *    this is achieved by setting the value of WooCommerce::api (typically accessed via 'WC()->api') to an instance of this class.
 *
 * DO NOT add any additional public method to this class unless the method existed with the same signature in the old WC_API class.
 *
