Launched 26 August 2026. This is early access. Everything listed here is published and checksummed, and that part is not provisional. Two things are still arriving: the newest hours read audit pending until the coverage pass reaches them, and per-row capture provenance (which machine recorded each row) is being added to new hours, with the historical backfill to follow. Anything this site states as measured has been measured.

Checksums for this prefix: SHA256SUMS.txt, verify a download with sha256sum -c.

Download this prefix in bulk

You do not need to open the hour pages, and you should not scrape this one. SHA256SUMS.txt lists every file under this prefix, so it is both the download list and the verification file.

# every file URL under /v3/2026-08-19/18/
curl -s https://archive.pendulumflow.com/v3/2026-08-19/18/SHA256SUMS.txt | awk '{print $2}' \
  | sed 's|^|https://archive.pendulumflow.com/v3/2026-08-19/18/|'

# fetch them, four at a time, keeping the directory layout
curl -s https://archive.pendulumflow.com/v3/2026-08-19/18/SHA256SUMS.txt | awk '{print $2}' \
  | xargs -P4 -I{} curl -sf --create-dirs -o {} https://archive.pendulumflow.com/v3/2026-08-19/18/{}

# then verify the lot, in the directory you downloaded into
curl -sO https://archive.pendulumflow.com/v3/2026-08-19/18/SHA256SUMS.txt && sha256sum -c SHA256SUMS.txt

Add | grep 'parquet$' to skip the manifests. Ranges within a file work too, see the format notes.
