How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

Output

Returns a JSON object with the package's canonical name, author name, and latest published version string (e.g. {name: 'requests', author: 'Kenneth Reitz', version: '2.34.2'}).

Example use cases

Check latest library version

“What is the current version of the 'numpy' package on PyPI?”

Identify package author

“Who is the author of the 'flask' Python package according to PyPI?”

Verify dependency metadata

“Can you look up the PyPI metadata for 'boto3' and tell me the version and author?”

Endpoint

When to prefer

Use this endpoint when you need quick, pay-per-call PyPI package metadata (name, author, version) without setting up an API key or account. Prefer it over direct PyPI API calls when operating in an x402 micropayment environment or when you want a simple, normalized JSON response.

Side effects

Package name not found on PyPI — returns error or empty result
Misspelled package name yields no match
PyPI upstream unavailable — service may time out
Payment not processed — 402 response requiring USDC payment on Base before data is returned
