# Get apidatasets versions arrays chunks

> GET /datasets/{dataset_id}/versions/{version_id}/arrays/{array_name}/chunks/{chunk_path}

Returns 503 + Retry-After while real Zarr bytes are
deferred-pending-zarr. Once zarr-python lands the view 302s to a
presigned S3 URL — clients never see raw bucket / key tuples.

The full path through the URL ensures every request goes through
the per-version visibility check; there is no direct-to-S3 path.
