Example prompt: Search for deprecation notices and official successor packages for 'request' npm library — give me up to 5 results so I can figure out what our team should migrate to.

## When to prefer this

Use this endpoint when you need current, live web information about whether a specific software package has been officially deprecated and what its recommended successor is — especially for research teams auditing dependencies or planning migrations. Prefer this over static registries when you need synthesized search results from across the web, including blog posts, changelogs, and official announcements.

## Known failure modes

- No deprecation information found if the package is not deprecated or has limited web coverage
- Irrelevant results if the query is too broad or the package name is ambiguous
- Live web search may return outdated or unofficial sources
- Rate limiting or service unavailability may prevent results from being returned
