Alpha (Mossland) vs Solana JSON RPC
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.
Solana's public JSON-RPC clusters expose the full read/write RPC surface — accounts, transactions, blocks, and WebSocket subscriptions — with no signup or API key required. They're free to call, but Solana's own docs are explicit that the shared public endpoints are rate-limited to roughly 100 requests per 10 seconds per IP and are not intended for production traffic, pointing serious usage toward a dedicated third-party RPC provider instead.
