Alpha (Mossland) vs MercadoBitcoin
Alpha is Mossland's free, keyless public API that turns Korean-language crypto YouTube/news/macro chatter plus Mossland's own on-chain activity into a queryable knowledge base of canonical entities, topics, and events. Its /api/ask endpoint answers natural-language questions in Korean or English with citations back to source videos or briefs, and a companion MCP server exposes 12 tools for Claude Desktop, Cursor, and similar agent clients over JSON-RPC. Every surface is HTTPS-only with no signup, though the docs note unauthenticated abuse may trigger a per-IP rate cap.
Mercado Bitcoin is Brazil's oldest and largest cryptocurrency exchange, operating since 2013 with spot trading across dozens of BRL pairs. Its v4 REST API and companion WebSocket service expose public market data — candles, order books, tickers — without authentication, while trading and account endpoints require an API key created from account settings. The API is free to use for individual developers.
