## When to prefer this

Choose this endpoint when you need up-to-date, live-web-sourced information about API changes, breaking updates, or new endpoint releases for any API provider. It is especially useful when official documentation is not yet indexed in your knowledge base or when you need current information beyond a training cutoff. Prefer it over static documentation lookups when recency matters.

## Known failure modes

- Vague query returns irrelevant or mixed results not specific to the intended API
- Live web search fails to find an official changelog if the provider does not publish one publicly
- max_results set too low may miss important recent changes
- Query may surface community blog posts instead of official release notes if the official changelog is not well-indexed
- Rate limiting or upstream search service unavailability returns an error
