The 0xinsider API gives you programmatic access to the same intelligence powering the 0xinsider terminal — trader grades, whale trade signals, smart money flow, and insider detection across Polymarket and Kalshi. The same data is also available through the live @0xinsider/mcp package for Claude Code, Cursor, Codex, Gemini CLI, and other MCP clients.

​
What you can build

  • Trading bots that react to whale trades and smart money signals in real-time
  • AI agents that analyze trader performance and market intelligence
