PyPI distribution footprint, daily

Start here — free verify: https://councilof.ai/gspc-verify/ (or the free MCP tool verify_card at https://councilof.ai/mcp) · Full catalog: https://councilof.ai/catalog.json · Methodology: https://councilof.ai/methodology/ · Measurement, not certification.

One JSON record a day: how many times the packages published from our PyPI account were downloaded, as counted by pepy.tech. Published by Council of AI (CSOAI Ltd, UK Companies House 16939677). GET https://councilof.ai/api/momentum reads latest.json from this dataset.

Files

• latest.json: the newest record (totals, windows, entity shares, package list source, every package).
• latest-packages.jsonl: the same day's packages as flat rows, one per package, for the dataset viewer.
• daily/pypi-footprint-YYYY-MM-DD.json: every record, one per UTC day, never rewritten.

How the record is made

1. Which packages. Read fresh every run from PyPI's own role table: XML-RPC user_packages(account) on https://pypi.org/pypi lists every project on which the account holds the Owner or Maintainer role. package_list names the method and the time it was read. If the role table does not answer, the run uses the committed list at https://councilof.ai/interop/footprint-packages.json and says so.
2. Who published each one. CSOAI Ltd and MEOK AI Labs publish from the same PyPI account. Every row carries an entity label and every row is counted. by_entity prints each share beside the total.
3. The count. https://pepy.tech/api/v2/projects/<name>, one request a second. all_time is pepy's total_downloads. last_30d, last_7d and prev_7d are summed from pepy's per-day map over complete UTC days, and each window is named in the record.

Limits

• These are registry download events, including mirrors, CI and automated traffic. They are not people, installs, users or customers.
• All-time, 30-day and 7-day figures are separate windows. They are never added to each other.
• If any package's counter does not answer, the record says PARTIAL. Every sum is then a lower bound over n_counted packages, not a total over n_packages, and the packages that did not answer are listed in failed. A missing value is null, never 0.

Producer

scripts/pypi-footprint/pypi_footprint.py in the councilof-ai repository, run daily on a small always-on host. It measures and publishes a count. It does not post, register or sign anything.
