# Best Buy Developer API (slim)

> Best Buy's Developer API gives read access to the BESTBUY.COM catalogue, prices, availability, categories, US stores, recommendations and open-box listings with a free API key. Ordering through the Commerce API is invite-only for partners.

**E · 39.1/100 · rank #991 of 1076 · #4 in Shopping, returns & refunds · not agent-ready · confidence medium**


Assessment: A free key with published limits of 5 calls a second and 50,000 a day opens catalogue, price and store-availability search, with field selection and cursor paging. Ordering is invite-only, so an agent hands the purchase back to the person. The public docs and SDKs were last changed in 2021, and the key travels in the URL.

## Before you call it

1. Add format=json to Products, Stores and Categories calls. XML is the default for those three
2. Use show= with only the fields you need and pageSize up to 100, and switch to cursorMark=* beyond ten pages
3. Batch SKU lookups with the in operator to stay under 5 calls a second. A 403 can mean the limit, not a bad key
4. Send the person to the product URL to buy. The Commerce API that places orders needs a partner invitation
5. Cache responses for no more than 72 hours and refresh prices before quoting them, as the terms require

## Connect

```bash
curl 'https://api.bestbuy.com/v1/products(categoryPath.name="All Flat-Screen TVs")?format=json&show=sku,name,salePrice&sort=salePrice&apiKey=YourAPIKey'
```
