MercadoPago
MercadoPago is Mercado Libre's payments platform for Latin America, offering Checkout Pro (hosted checkout), a transparent Checkout API, in-person Point terminals and QR payments, subscriptions, and post-sale operations like refunds, chargebacks, and disputes. Requests authenticate with Bearer-token application credentials and return JSON over HTTPS from a single api.mercadopago.com endpoint shared across countries. A live Origin-header probe confirmed CORS is enabled (Access-Control-Allow-Origin echoes the request origin on both GET and OPTIONS), and merchants pay per-transaction processing fees rather than a subscription.

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