BuyWhere vs Descripio Amazon Reviews

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.

Descripio Amazon Reviews is a live async review-aggregation API that pulls and caches Amazon product reviews across a dozen marketplaces, returned as JSON once a scrape job completes. It is gated by a Bearer API key on a tiered free-plus-paid plan, though cached-review reads stay unlimited and free on every tier. The live host cleanly enforces auth, rejecting both missing and invalid keys, but returns no CORS headers for cross-origin browser calls.
