How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

A JSON response indicating success and containing version data for the requested Python package from PyPI, including available release versions.

Example use cases

Check library version before install

“Can you look up all available versions of the 'pydantic' package on PyPI? I want to know if version 1.10.0 exists before I pin it in my requirements.txt.”

Find latest stable release

“What's the most recent version of 'fastapi' published on PyPI? I need to update my project's dependency.”

Audit dependency version history

“List all the versions of 'boto3' that have been published on PyPI — I'm trying to figure out which versions were available before mid-2023.”
