# Catalog

The Catalog endpoints in the B2B Edition Storefront API enable you to retrieve product and variant information from a BigCommerce store. These endpoints are designed for fast, programmatic access to variant data, supporting use cases such as catalog display, quick ordering, and integration with external systems.

Use these endpoints to:

* List variants for a specific product (`/catalogs/variants`)
* Fetch details for one or more variants by SKU (`/catalogs/quick-product`)
* Retrieve comprehensive variant data for quick order workflows (`/catalogs/quick-order-pad`)

All endpoints require a Bearer token for authentication. For details, see the [REST Storefront API authentication guide](/developer/docs/b2b-edition/getting-started/authentication#storefront-tokens).

These endpoints mirror the functionality of standard BigCommerce REST API endpoints and provide data similar to Storefront GraphQL API queries like `productVariantsInfo` and `variantSku`. For more information, see the [GraphQL Playground](https://api-b2b.bigcommerce.com/graphql/playground).
