How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
A JSON object containing the package's canonical name, current version, author, license, one-line summary, home page URL, project URLs map, list of required distribution packages (requires_dist), and required Python version string.
Example use cases
Dependency audit for a Python project
“Can you look up the PyPI metadata for 'boto3' and tell me what packages it depends on and what Python version it requires?”
License compliance check
“What license does the 'cryptography' package use on PyPI? I need to make sure it's compatible with our project.”
Quick package overview before installing
“Give me a summary of what the 'fastapi' package does, who maintains it, and what version is currently on PyPI.”
Technical details
Endpoint
GEThttps://fastx402.tools/pypi-package-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs structured PyPI package metadata without setting up an API key or account. Ideal for dependency audits, license checks, version lookups, or enriching package information in automated pipelines. Prefer over scraping PyPI HTML or using the raw PyPI JSON API directly when a pay-per-call micro-payment model is acceptable and no authentication setup is desired.
Side effects
- Package name not found on PyPI — returns an error or empty response
- Typo in package name yields no results
- Package exists but has incomplete metadata (e.g. no author or license field)
- PyPI API temporarily unavailable — upstream timeout
