Source OpenAPI: 0xArchive API 1.5.0; 116 paths; 90 component schemas. Get historical order book snapshots within a time range with configurable resolution. Checkpoint history starts January 29, 2026; 30s/10s/1s start January 30, 2026. Use ‘granularity’ parameter to control data resolution (tier restrictions apply). Tick-Level Data (Enterprise tier only): When granularity=tick, the response format changes. Instead of returning snapshots in the data array, it returns: - checkpoint: Full orderbook state at the start of the time range - deltas: Array of incremental changes to apply to the checkpoint This is the most efficient format for reconstructing high-frequency orderbook states. Use the SDK’s OrderBookReconstructor class for client-side reconstruction.
