How it fits together
Read the diagram top-down. Pick the surface you need. Mix freely — most real integrations use REST + WebSocket together, with tick downloads for backtesting and MCP for agent-driven flows.The three data products
Real-Time WebSocket
The fastest feed in prediction markets. Mempool access streams pending transactions before they confirm — up to 5 seconds faster than Polymarket’s RTDS.
Orderbook Tick History
Every placement, update, cancel, and fill — the raw tick stream at every granularity, downloadable as Parquet. New.
Blockchain-Indexed Analytics
Wallet P&L, smart-money flow, leaderboards, and positions — indexed straight from the chain, accurate to the block.
