Download Tick Data

Changed on

Download raw, tick-level history as signed Apache Parquet URLs. Returns a list of Parquet parts (each with its row/byte counts and ID/time coverage range) plus the dataset schema. Feed the signed URLs into your own DuckDB, Polars, pandas, or Spark.

Releasing soon — this dataset is in a gated private preview and is not yet reachable with a standard API key.

Finalized data only: raw ticks are compacted daily at 06:00 UTC, so requests for today/future (or any day without a manifest) return 404 not_final. Pick the day(s) with exactly one of date, start_date+end_date, or start_time+end_time (epoch ms). Signed URLs expire after ~1 hour.
