How this service works
Check PyPI package metadata, release age, yanked status, Python requirements, dependencies, license, and OSV vulnerabilities.
Output
Returns structured metadata about the requested PyPI package including: release timestamp and age, yanked status and reason, declared Python version requirements, direct dependencies, SPDX license identifier, and a list of OSV vulnerability advisories with severity and CVE references where available.
Example use cases
Security audit before dependency install
“I'm about to add cryptography 41.0.3 to my requirements.txt — can you check PyPI for any known OSV vulnerabilities, whether it's been yanked, and what license it uses?”
Checking freshness of a stale package
“Is the PyPI package Pillow 9.0.0 still current and safe to use? I want to know its release age, whether it's been yanked, and if there are any open security advisories.”
Validating Python compatibility for a package
“Does the latest version of numpy on PyPI support Python 3.12? Also tell me if it has any known vulnerabilities and what its dependencies look like.”
Technical details
Endpoint
GEThttps://nohands-coinbase-bazaar.bytoken2023.workers.dev/v1/x402/software/pypi-package-preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or developer workflow needs to vet a Python package before installation or inclusion in a project — especially when security, licensing compliance, or maintenance health are concerns. Prefer this over manual PyPI browsing when you need a structured, machine-readable preflight signal that combines metadata, vulnerability data (OSV), and yanked status in a single call. Ideal for CI/CD pipeline agents, dependency review bots, or autonomous coding agents that install packages on behalf of users.
Side effects
- Package name not found on PyPI — returns 404-style error
- Specific version not found — falls back to latest or returns error
- PyPI API unavailable — upstream timeout or service error
- Malformed package name input — validation error
- OSV database query fails — vulnerabilities field may be empty or flagged as unavailable
