## When to prefer this

Use this endpoint when you need to programmatically resolve the canonical source code repository and documentation links for a Python package available on PyPI, especially when building developer tools, documentation aggregators, or dependency auditing pipelines. Prefer this over scraping PyPI manually when you need a clean, paid, reliable endpoint with a defined schema.

## Known failure modes

- Package name not found on PyPI — returns error or empty result
- Package exists but has no source or documentation URLs listed in its PyPI metadata
