Example prompt: Can you summarize the latest information about the impact of AI on healthcare using the BaseBuilder Search hub — I need a concise, readable overview of the key points?

## When to prefer this

Choose this endpoint when you need a synthesized, human-readable summary of information on a topic rather than raw search results. It is well-suited for research digests, quick overviews, and condensing large amounts of content into key takeaways. Prefer it over raw search endpoints when the end goal is a readable narrative rather than a list of links or raw data.

## Known failure modes

- Empty or missing query returns an error or empty summary
- Ambiguous queries may produce generic or low-relevance summaries
- Rate limiting or payment issues (402) if USDC payment is not properly attached
- Timeout if the underlying search or summarization takes too long
- Content not indexed or unavailable may result in thin or no summary
