- SerpApi Google Shopping API: Seeing what Google Shopping shows for a query, across many stores, without a seller account.
Side by side
| Best Buy Products API | SerpApi Google Shopping API | |
|---|---|---|
| Searches | Best Buy's catalog of over a million products, current and discontinued, with pricing, availability, specifications, descriptions and images. | Google Shopping results for a query, localised by country (gl) and location. |
| Returns | Product records with sale and regular price, a BESTBUY.COM product page URL and an add-to-cart URL, plus specs and images. | Position, title, price, rating, source (store) and a link per result, plus a token for a detailed product page. |
| Before the first call | A developer account and an API key, requested with an email address and activated from the emailed instructions; calls are limited per key. | A SerpApi account and API key. |
| Free | Not stated on its pages | Free plan: 250 searches a month; only successful searches count. |
| Paid | Not stated on its pages | Starter plan $25 a month for 1,000 searches. |
| Acting on a result | Buy link: each product has a BESTBUY.COM product URL and an addToCartUrl; checkout through the separate Commerce Gateway API needs Best Buy's pre-approval. | Each result links to its Google Shopping page and names the store; no checkout. |
| Limits on keeping or showing results | Content may be cached only temporarily, for no more than 72 hours, and only to speed up display; content must be attributed to Best Buy. | SerpApi keeps search data for 31 days, or not at all with its ZeroTrace mode (Enterprise only); its legal cover is for collecting the data, not for how you use it. |
| Coverage | BESTBUY.COM (United States); the Stores API covers stores in the US and Puerto Rico. | Any country Google Shopping serves, chosen with the gl country code. |
| MCP server | No official server listed | Official hosted MCP server at mcp.serpapi.com (needs a SerpApi API key). |
