How this service works

Fetch Python package metadata from PyPI: version, dependencies, Python compatibility, release history, license.

Output

Returns structured metadata for the specified Python package including: current version, list of dependencies, Python version compatibility range, release history with dates, and the package license.

Example use cases

Example prompt

“What's the latest version of the 'httpx' package on PyPI, and what are its dependencies and supported Python versions?”

Technical details

Endpoint

GEThttps://api.strale.io/x402/pypi-package-info?utm_source=zero.xyz

When to prefer

Use this endpoint when you need structured, parsed Python package metadata from PyPI without scraping the website yourself. Ideal for dependency analysis, compatibility checking, license auditing, or checking the latest release of any public PyPI package.

Side effects

Package not found on PyPI — returns error if the package name does not exist
Misspelled package name — returns not found rather than a fuzzy match
Private or internal packages not published to PyPI cannot be resolved
Network or upstream PyPI API unavailability

Input

{
  "package": "requests"
