Mercado Envios

Distinct logistics/fulfillment layer from the Mercado Livre marketplace itself (already cataloged separately under Retail/CRO-271 as `mercado-livre`) — blends third-party carriers with proprietary warehousing and delivery. Handles an estimated 95% of Brazilian deliveries via its own infrastructure (1.2B+ items shipped globally in 2024, 10 distribution centers in Brazil expanding to 21 by end of 2025). Has a public developer API (developers.mercadolivre.com.br/pt_br/mercado-envios) for shipment creation/tracking; portal returned HTTP 403 to automated fetch but is a real, documented Mercado Livre developer program endpoint.
