BuyWhere vs Lazada

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.

Lazada's Open Platform gives registered sellers and partners programmatic access to product, order, and seller-performance data across its Southeast Asian marketplaces. Every call must carry an HMAC-SHA256 signature derived from an app key/secret pair rather than a plain bearer token, confirmed live by a MissingParameter error demanding the app_key. Access requires an approved developer application tied to an active Lazada seller account, at no separate charge.
