# PMAxis — The data layer for prediction markets

> Live markets, trades, orderbooks, and signals. One API for AI agents.

PMAxis ([https://pmaxis.trade](https://pmaxis.trade)) aggregates prediction market data (currently Polymarket) behind one developer-friendly interface: a REST API, a WebSocket stream, and an MCP server for AI agents.

## What you get

- **Signals & analytics** — momentum signals, crowd sentiment, wallet P&L, calibration (Brier scores), and Sybil-style wallet clustering
- **Agent-native access** — an MCP server with 60+ tools plus a REST API with OpenAPI docs; free tier includes 5,000 credits/month
