# Download simulation time series parquet

> Redirect to a short-lived signed URL for ``time_series.parquet``.

Most HTTP clients follow redirects automatically, so the caller receives
the parquet bytes transparently. Replaces the JSON ``/result`` endpoint
for time-series downloads. Pass ``redirect=false`` to get ``{"url": ...}``
instead — browsers must fetch the signed URL themselves (see
``_simulation_parquet_download``).
