Example prompt: Can you look up the declared PyPI dependencies for Flask — I want to see exactly which packages it requires at install time?

## When to prefer this

Use this endpoint when you need a live, up-to-date view of a Python package's declared dependencies directly from PyPI without scraping the site yourself. It is especially useful for dependency auditing, supply chain analysis, or building tooling around package metadata. Prefer it over static lockfiles or cached data when freshness matters.

## Known failure modes

- Package name does not exist on PyPI — returns an error or empty result
- PyPI is temporarily unavailable — request may time out or return a service error
- Package has no declared dependencies — returns an empty list
- Misspelled package name — returns not-found error
