PyPI Changelog Between Versions
PyPI changelog between two versions of a Python package: the full release notes of every version in the range (newest first, up to 100) from the project's changelog file and GitHub releases, with publish dates, bump type, yanked flags, extracted breaking changes and Requires-Python / dependency changes. One call instead of reading a long HISTORY or CHANGES file before a Python package upgrade.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Using Roundhouse, look up the x402 service PyPI Changelog Between Versions and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=PyPI%20Changelog%20Between%20Versions' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://upgrade-brief.shopttyass-85f.workers.dev/pypi/changelog, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
