Best Buy vs WooCommerce

Best Buy's public REST API exposes product, store, category, and recommendation data behind a free API key registered through its developer portal. Responses can be returned as either JSON or XML for most endpoints, though the newer Recommendations endpoints are JSON-only. Live probing shows the gateway actively validates keys server-side but returns no CORS headers, so it is built for server-side integration rather than direct browser calls.

WooCommerce's REST API isn't a centrally hosted service — every self-hosted WooCommerce store exposes its own instance, authenticated by a consumer key/secret pair sent as HTTP Basic Auth credentials over HTTPS, per WooCommerce's own documentation. Because CORS support depends entirely on each merchant's own server configuration rather than the protocol itself, it can't be verified as a single blanket property of "the API." The protocol ships free with the open-source plugin; the only cost is whatever the merchant already pays to host their own store.
