Mercadolibre vs Rappi

Mercado Libre exposes a large REST surface across its Latin American marketplace sites, covering listings, orders, ads, and shipping. Public reference data like site categories is reachable without a token, but anything scoped to a seller account requires an OAuth2 access token obtained via an authorization-code or client-credentials grant. The API itself carries no direct usage fee — Mercado Libre monetizes through marketplace and payment commissions instead.

Rappi's public API lets approved merchant partners manage store menus and orders across its Latin American on-demand delivery platform. Access requires a formal partnership and uses OAuth2 — Authorization Code with PKCE for partner-facing flows, plus Auth0-issued bearer tokens for machine-to-machine calls — confirmed live against its login/token gateway. Each country Rappi operates in runs its own regional API host.
