Field notes
The catalog lists Polymarket and Binance spot and perpetual data as live, with history shown from June 2025; Kalshi and Hyperliquid are marked “Coming soon,” although the page also says they are recording now. Delivery options include REST, WebSocket, daily Parquet/CSV, S3, and MCP, and sample files are offered without login. Coverage has explicit bounds—for example, Binance focuses on roughly the top 20 USDT pairs.
