What tariff should I use or how much does it cost?

What tariff do I need to use to use these features: JS Buy SDK, Buy JS button, Shopify  Storefront API?

All Shopify Plans give access to these features.

Thank you very much! Instagram facebook shopify app, built-in marketing and analytics tools, as well as sales channels, for example, facebook/instagram, and at the same time it's all at a minimum tariff of$9/month, could you still tell me if I plan to use the showcase api for headless commerce, will there be an opportunity to use applications: shopify app, built-in marketing and analytics tools, as well as sales channels, for example, facebook / instagram? If this is not possible, can you specify the path to use shopify fully in your framework/website, taking into account my needs outlined above? Thank you very much!!

If you are going to use Shopify Buy SDK on your non-Shopify website, you can still have access to all marketing channels like Facebook and Instagram and you can use any app developed for Shopify backend that help you to run your store operations.

Instead many frontend apps will not work on your website out-of-the-box if you are not going to use Shopify platform to show your frontend store.

Be careful because it is not easy process going headless if you are not a developer or if you don't have a good developer/agency supporting you.
