PyPI Package Stats

A Python library and optional CLI tool for PyPI package stats and download analytics, built on the official pypistats API. Fetch daily, weekly, monthly, and 180-day downloads, Python version and OS breakdowns, package metadata, with smart disk caching.

Features

• Package Metadata: Name, version, description, author, license, home page, and PyPI URL
• Download Statistics: Last day, week, month, and 180-day download counts
• Python Version Breakdown: Top 5 Python versions with download percentages (last 30 days)
• Operating System Distribution: Top 4 operating systems with download percentages (last 30 days)
• Dual Interface: Use as a CLI tool or import as a Python library
• Flexible Output for CLI: Human-friendly Rich tables or machine-readable JSON
• Python API: Clean, type-safe API with structured data models
• Smart Disk Caching: Persistent disk cache with configurable TTL (default: 1 hour)
• Cache Management: Inspect cache usage or clear cached responses programmatically or via CLI

Installation

Install the library (no CLI dependencies):

pip install pypi-package-stats

Install with CLI support:

pip install pypi-package-stats[cli]

Library Usage

from pypipackagestats import get_package_stats

# Get package statistics
stats = get_package_stats("requests")

# Access structured data
print(stats.package_info.name)        # "requests"
print(stats.downloads.last_month)     # 123456789

# Convert to dictionary (for JSON serialization)
data = stats.to_dict()

Advanced Options

from pypipackagestats import get_package_stats, clear_cache, get_cache_info

# Disable caching for fresh data
stats = get_package_stats("requests", no_cache=True)

# Custom cache TTL (5 minutes = 300 seconds)
stats = get_package_stats("django", cache_ttl=300)

# Clear all cached responses
clear_cache()

# Get cache statistics
cache_info = get_cache_info()
print(f"Cache size: {cache_info['size']} entries")
print(f"Cache directory: {cache_info['directory']}")

API Reference

Functions

Function	Description
get_package_stats(name, *, no_cache=False, cache_ttl=None)	Fetch all statistics for a PyPI package. Returns a PackageStats object.
clear_cache()	Clear all cached API responses.
get_cache_info()	Return cache size and directory information.

CLI Usage

Requires the cli extra: pip install pypi-package-stats[cli]

Command	What you get
pypi-package-stats package <name>	Main view (metadata + downloads)
pypi-package-stats package <name> --json	Machine-friendly JSON output
pypi-package-stats package <name> --no-cache	Bypass cache for this request
pypi-package-stats package <name> --cache-ttl <seconds>	Set custom cache TTL
pypi-package-stats cache-clear	Remove all cached responses
pypi-package-stats cache-info	Show cache statistics
pypi-package-stats --help	Show help message

Example:

pypi-package-stats package nestedutils --json

Data Source & Rate Limiting

This tool uses the pypistats API to fetch PyPI package statistics. The API enforces IP-based rate limits (for example, ~5 requests/sec and ~30 requests/min at the time of writing). These limits are set by pypistats.org and may change over time.

The built-in caching system helps minimize API calls and reduce the chance of hitting rate limits. If you encounter rate limit errors, wait a few seconds between requests if making multiple queries.

Limitations

• Python version and OS breakdowns are limited to the last 30 days
• Data availability depends on the pypistats service
• Data is usually 24-48 hours behind (pypistats limitation)

Use Cases

• Compare popularity of Python libraries
• Track adoption trends of your own packages
• Generate download statistics for reports or dashboards
• Automate analytics workflows using the library API or CLI JSON output
• Integrate PyPI stats into your Python applications
• Build custom dashboards and monitoring tools
