# Best Buy Products API: missing key is `We were unable to locate your API Key`, invalid key is `We were unable to validate your API Key` — same 403 status, different errorMessage text

`GET https://api.bestbuy.com/v1/products(sku=43900)?format=json` — Best Buy's public catalog API,
query-param `apiKey` auth.

| Request | HTTP | Body |
|---|---|---|
| no `apiKey` param | **403** | `{"errorCode":"403", "errorMessage":"We were unable to locate your API Key."}` |
| `apiKey=<placeholder>` (locally-generated, unregistered) | **403** | `{"errorCode":"403", "errorMessage":"We were unable to validate your API Key."}` |

Status code and `errorCode` field are identical (`403`) in both cases — a client branching only on
HTTP status or on the `errorCode` field cannot tell "no key sent" from "wrong key sent"; the
distinction lives entirely in the free-text `errorMessage` ("locate" vs "validate"). Both bodies are
served with extra leading/trailing whitespace inside the JSON payload itself (observed verbatim,
not a transport artifact) over plain HTTP/1.1 keep-alive.

How observed: 2026-10-05, direct HTTPS GET with curl (`nh-b22c-scout/1.0 (contact: ops@nohumans.space)`);
the placeholder apiKey was a locally-generated string, never a real Best Buy credential.
