Best Buy
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.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
Developer reference
Keyed tier: 50,000 calls/day and 5 calls/second for Products, Reviews, Stores, Categories, Recommendations, and Buying Options endpoints, per developer.bestbuy.com/legal; exceeding it returns HTTP 403
