How this service works
PyPI project facts: latest version, Python requirement, license, release freshness and whether the latest is yanked.
Output
A JSON object containing: package name, latest version, Python requirement string, SPDX license identifier, upload dates (first and last), days since last upload, total release count, whether the latest version is yanked, a health verdict (e.g. maintained/stale/abandoned), a human-readable summary, reasons behind the verdict, dependency count, home page URL, source repository URL, and an asOf timestamp indicating data freshness.
Example use cases
Vetting a new Python dependency
“Before I add 'pydantic' to my project, can you pull its PyPI facts — latest version, license, Python requirement, and whether the latest release is yanked?”
Checking if a package is abandoned
“I'm worried 'celery' might be going stale — can you look it up on PyPI and tell me how long it's been since the last release and what the health verdict is?”
License compliance review
“I need to know what license 'cryptography' uses on PyPI before we ship it in our product — can you grab that along with the latest version number?”
Technical details
Endpoint
GEThttps://package-health.x402tookit.com/pypi-package?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, single-call summary of a PyPI package's health signals — version, license, freshness, and yank status — without scraping PyPI directly. Prefer it over the multi-ecosystem endpoint when you specifically need PyPI-only data with no overhead. Choose it over the version-history endpoint when you only need the latest release facts rather than a full release timeline.
Side effects
- Package name not found on PyPI — returns null fields or error
- PyPI API unavailable — degraded flag set to true with partial data
- Yanked release with no reason provided — reasons array empty
- Package with no releases — most numeric fields null
- Misspelled package name returns empty or irrelevant results
