Alpha (Mossland) vs Gemini
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.
Gemini's REST and WebSocket APIs cover public market data (tickers, order books, trade history) alongside authenticated endpoints for order placement, account status, and FIX Drop Copy. Public market-data calls need no credentials, while trading and account endpoints require an HMAC-signed API key/secret pair with role-based permissions such as separate Trader and Fund Manager roles.
