BuyWhere vs WooCommerce

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.

WooCommerce's REST API isn't a centrally hosted service — every self-hosted WooCommerce store exposes its own instance, authenticated by a consumer key/secret pair sent as HTTP Basic Auth credentials over HTTPS, per WooCommerce's own documentation. Because CORS support depends entirely on each merchant's own server configuration rather than the protocol itself, it can't be verified as a single blanket property of "the API." The protocol ships free with the open-source plugin; the only cost is whatever the merchant already pays to host their own store.
