fully featured API ?

hi everyone, I'm wondering if the API is fulle accisble to any kind of licenses of the plugin (free vs pro) ? I'm not a dev and I'm using claude code to help me creating a headless wordpress and I'm actually trying to implement a mini eshop through the API. For some reasons I'm unable to acces the wp-json/fluent-cart/v2/products/4083 to have acces to my products datas.
