How this service works
Was a PyPI release yanked? Exact version check with the maintainer's reason, upload date and file count.
Output
Returns a structured object with: yanked (boolean), yankedReason (the maintainer's stated reason), uploaded (ISO date of the release), files (count of distribution files), requiresPython (version constraint), verdict (human-readable summary), summary, sourceUrl, and degraded/notChecked flags if the check was partial.
Example use cases
Auditing pinned CI dependencies
“Our CI pipeline pins requests==2.19.0 — can you check if that exact version has been yanked on PyPI and tell me the reason if so?”
Investigating a failed pip install
“pip is warning me that urllib3 1.26.4 may have been yanked — can you look it up and tell me the maintainer's reason and when it was originally uploaded?”
Supply chain safety check before deploy
“Before we deploy, verify whether Django 3.2.14 has been yanked from PyPI and give me the verdict summary and file count for that release.”
Technical details
Endpoint
GEThttps://package-health.x402tookit.com/pypi-yanked?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check a single, exact PyPI package version for yanked status — particularly in CI/CD pipelines, dependency audits, or supply chain security workflows. Prefer this over generic package health endpoints when the yanked/yank-reason signal is the primary concern, rather than license, provenance, or adoption metrics.
Side effects
- Package name or version not found on PyPI — returns null fields or an appropriate error
- Yanked reason not provided by maintainer — yankedReason field may be null even when yanked is true
- PyPI API unavailable — degraded flag set to true with partial data
- Invalid version string format — query returns no match
- Rate limiting or upstream timeout from PyPI
