Cubesphere (cubesphere.xyz, branded CubeSphere) is a Korean-language crypto market intelligence platform that tracks about 270 coins, puts news, trending, exchange listings, on-chain and corporate treasury events on one timeline, and tags each event to coins and categories. It also runs Cubesphere Data (beta), which pulls SEC EDGAR Form 4, Form 144 and Schedule 13D/G insider filings and serves them as clean economic events through an HTTP API (api.cubesphere.xyz) and an MCP server (mcp.cubesphere.xyz) that AI agents can query. A free tier gives 24-hour-delayed data; basic and pro tiers use an X-API-Key.
