BuyWhere
BuyWhere runs a live product-search API backed by a real, large product catalog spanning merchants across seven Southeast Asian and North American markets, purpose-built for AI shopping agents. Access is gated by a Bearer API key with a published free/Starter/Pro/Enterprise pricing ladder rather than an open, unauthenticated feed. Its CORS policy only serves an Access-Control-Allow-Origin header to allow-listed origins, so arbitrary browser-side callers get no such header even though the API answers preflight requests.

Auth quickstart
- 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.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
