How this service works
Looks up normalized package metadata from the Python Package Index, version, dependencies, license, homepage, and yank/deprecation status, trimmed down from the much larger raw index response. For agents auditing or generating requirements files before running pip install.
Output
A normalized subset of PyPI index data for the specified package, including current version, dependency list, license type, homepage URL, and any yank or deprecation flags — trimmed from the full raw PyPI response for agent-friendly consumption.
Example use cases
Example prompt
“Before we run pip install, can you look up the PyPI metadata for the 'requests' package — I want to check its current version, license, dependencies, and whether it's been yanked or deprecated?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/pip-dependency-lookupWhen to prefer
Use this endpoint when an AI agent needs to audit, generate, or validate a Python requirements file before running pip install, or when checking package provenance, license compatibility, or deprecation status. Prefer this over raw PyPI API calls because the response is pre-normalized and trimmed to the fields most relevant for dependency auditing.
Side effects
- Package name not found on PyPI — returns error or empty result
- Package exists but has no published releases — metadata may be incomplete
- Misspelled package name returns no results
- PyPI upstream unavailable — service may return timeout or error
- Yanked-only packages may return limited metadata
