PyPI offers three RSS feeds, the Newest Packages Feed, the Latest Updates Feed, and the Project Releases Feed. You can also call its APIs to get more details on project activity.

Newest Packages Feed#

Available at https://pypi.org/rss/packages.xml, this feed provides the latest newly created projects on PyPI, including the package name, description and a link to the project page.

Latest Updates Feed#

Available at https://pypi.org/rss/updates.xml, this feed provides the latest newly created releases for individual projects on PyPI, including the project name and description, release version, and a link to the release page.

Project Releases Feed#

Available at https://pypi.org/rss/project/<project_name>/releases.xml for each project, this feed provides the latest releases for the given project on PyPI, including the package name and description, release version, and a link to the release page.

Project and release activity details#

PyPI publishes a “journal” of all project, package, and release activity (including Owner and Maintainer additions and removals, and source file and release additions and removals). You can query it with a mix of Mirroring Support and Simple Project API. Call changelog_last_serial() (in PyPI’s XML-RPC methods) to get the current revision of the journal (the last event’s serial ID), then look at /simple/ to get a list of all packages that currently exist. Subsequently, you can call changelog_since_serial(since_serial) with the serial ID you retrieved, and get the list of all actions that have occurred since then.

Example usage:

>>> import xmlrpc.client
>>> import arrow
>>> client = xmlrpc.client.ServerProxy('https://test.pypi.org/pypi')
>>> latefeb = arrow.get('2018-02-20 10:00:00')
>>> latefeb.timestamp
>>> latefebstamp = latefeb.timestamp
>>> recentchanges = client.changelog(latefebstamp)
>>> len(recentchanges)
>>> for entry in recentchanges:
...     if entry[0] == 'twine':
...         print(entry[1], " ", entry[3], " ", entry[2])

1.10.0   remove   1520025270

You could also request GET /simple/, and record the ETag, and then periodically do a conditional HTTP GET to /simple/ with that ETag included. A 200 OK response indicates something has been added or removed; if you get a 304 Not Modified, then nothing has changed.
