Prediction Market Intelligence API

active

SimpleFunctions provides a complete intelligence layer for prediction markets. Query 9,706+ live contracts across Kalshi and Polymarket with natural language. The world state endpoint compresses all active markets into ~800 tokens of structured context — perfect for feeding into AI agents. Use the thesis engine to decompose investment ideas into causal assumption trees, detect mispriced contracts, and monitor 24/7 for edge opportunities. Available as REST API, CLI (`npm install -g @spfunctions/cli`), and MCP server for Claude Code and Cursor.
