  • You trade XRP, DOGE, HYPE or BNB markets, or sports, weather and economics.
  • You want WebSocket, MCP, or an open-source backtester (resolvedkit) you can run locally.

To check the data before paying, the Free tier includes full-depth crypto books, or run resolvedkit on its bundled sample with pip install resolvedkit.
