Mercadolibre vs Rappi

Mercado Libre exposes a large REST surface across its Latin American marketplace sites, covering listings, orders, ads, and shipping. Two read-only lookups work without a token: a category by ID, such as `/categories/MLA1051`, and `/sites/{site}/domain_discovery/search`. Everything else, including site lists, currencies, item listings and search, needs an OAuth2 access token from the authorization-code flow. 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.
