When to use alternatives
a crypto-native platform: If you need crypto-native event markets or US macro forecasts with high liquidity. The GraphQL API gives you detailed order book data not available in aggregation layers.
a community forecasting platform: If you need extremely long-tail event types or want community forecasting on niche questions. No authentication required.
Platform D/strong>: If your application needs calibration data and historical track records for scientific or geopolitical forecasts.
