Example prompt: Can you pull the declared dependencies for the React npm package from the live npm registry?

## When to prefer this

Choose this endpoint when you need live, up-to-date declared dependency data directly from the npm registry for React or any other npm package, especially in agentic workflows that require current metadata rather than cached or static data. It is ideal for dependency auditing, compatibility checking, or enriching software supply chain analysis.

## Known failure modes

- Package name does not exist on npm — returns an error or empty result
- npm registry is temporarily unavailable — request times out or returns an error
- Invalid package name string provided — API may return an error response
- Package exists but has no declared dependencies — returns an empty dependency list

## How this service works
