How this service works
Latest-release metadata from the official PyPI JSON API (live): version, license, requires_python compatibility, requires_dist dependency specs (max 100), yanked flag, last upload time and project URLs. Query: ?pkg=requests. No personal author/maintainer data. 1h cache.
Output
Returns latest-release metadata for the queried PyPI package: current version string, SPDX license identifier, requires_python compatibility constraint, up to 100 requires_dist dependency specifiers, yanked boolean flag, last upload timestamp, and project URL map (homepage, source, documentation, etc.). Data is live from the PyPI JSON API with a 1-hour cache.
Example use cases
Example prompt
“Can you look up the latest PyPI metadata for the 'httpx' package — I want to know its current version, license, Python version requirements, and whether it's been yanked?”
Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/pypi/packageWhen to prefer
Use this endpoint when you need authoritative, structured PyPI release metadata — version, license, Python compatibility, and dependency specs — for a single package. Prefer it over scraping PyPI HTML or calling PyPI directly when you need a metered, cached, pay-per-call interface. Best for agent workflows that need to verify package details, audit dependencies, or check compatibility constraints programmatically.
Side effects
- Package not found on PyPI — returns 404 or error response
- Misspelled package name produces no results
- Package exists but has no releases — metadata may be sparse
- Cache may serve data up to 1 hour old if package was just updated
- Network timeout reaching PyPI upstream API
