# PyPI Versions List

> PyPI Versions List is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pypi-versions-list-49a7f920
```

Example prompt: Can you pull the full version history for the 'requests' package on PyPI, including release dates, any yanked versions, and how many releases there have been in the last 90 days?

## When to prefer this

Use this endpoint when you need a complete version history of a PyPI package including release dates and yanked flags, and want pre-computed summaries like recent release counts and first/latest dates — rather than scraping PyPI directly or calling the raw PyPI JSON API yourself.

## Known failure modes

- Package name not found on PyPI — returns error or empty result
- Package name is misspelled or case-sensitive mismatch
- PyPI API temporarily unavailable — upstream timeout
- Private/internal packages not listed on PyPI will not be found

## How this service works

All released versions of a PyPI project with release dates (from the first file upload of each release), yanked flags, total count, first/latest release dates, releases in the last 90 days and the 30 most recent. Python release-cadence helper. $0.01 per project.

## Output

Returns a structured object containing the full list of all released versions with their first-file upload dates and yanked flags, the total version count, the date of the first and latest release, the number of releases in the last 90 days, and a list of the 30 most recent releases.
