pypi-json
PyPI JSON API client library
Decision gist · record as of 2026-08-14
Yes. Low install friction, permissive MIT license, active maintenance, no known vulnerabilities, and typed code make this a straightforward choice if you need to query PyPI metadata from Python. The three-dependency footprint is minimal and all are well-established packages.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with a pure-Python wheel and only three runtime dependencies (apeye, packaging, requests).
- Actively maintained with a recent release in February 2026 and ongoing commits.

What it is and what it does
pypi-json is a Python client library that wraps PyPI's JSON API, allowing you to programmatically fetch package metadata, version history, dependencies, and other warehouse information without parsing HTML or managing HTTP requests directly. It depends on requests for HTTP calls, packaging for version handling, and apeye for URL management.
The library is typed, actively maintained, and supports Python 3.7 through 3.13 on both CPython and PyPy. It's useful when you need to integrate PyPI lookups into automation, build tools, or analysis scripts—anywhere you'd otherwise call the raw JSON API endpoints yourself.
Use it for
- Fetch package metadata and release history for dependency analysis or auditing tools.
- Build automation scripts that check PyPI for package updates or new versions.
- Analyze package dependencies and their transitive closure programmatically.
- Create package search or discovery tools that query PyPI without web scraping.
