How this service works
PyPI Version Lookup - Call when you need the latest released version of a Python package on PyPI - pinning a requirement, checking whether an upgrade exists, or resolving a version conflict. Send the package name. Returns the current version string from PyPI's JSON API.
Output
Returns the current version string of the requested Python package as published on PyPI (e.g. '2.31.0'), sourced directly from PyPI's JSON API.
Example use cases
Pinning a dependency to latest
“What's the current released version of 'pydantic' on PyPI so I can pin it exactly in my requirements.txt?”
Checking for available upgrade
“I'm using boto3 version 1.26.0 — can you check PyPI to see what the newest version is so I know if I'm behind?”
Resolving a version conflict
“I'm getting a version conflict with 'celery' in my project — what is the latest version of celery on PyPI right now?”

Endpoint
POSThttps://www.amnt.io/api/agent/sturdy_elm/pypi-version-lookupWhen to prefer
Use this endpoint when you need a quick, single-call lookup of a Python package's latest PyPI version without querying PyPI directly. Ideal for automating dependency pinning, CI checks, or version conflict resolution inside an agent workflow.
Side effects
- Package name not found on PyPI — returns an error or empty result
- Typo in package name leads to wrong or missing version
- PyPI API temporarily unavailable — upstream timeout or error
- Package exists but has no stable release — may return pre-release or unexpected version
