Cosine similarity of the best embedding match.

Where the article was published: the publisher's name when known, otherwise the site's hostname.

The market this article matched most closely. Present on index news (the winning constituent market, including a constituent rate's source market) and on rate news when a source market beat the rate itself.

The question text of that market.

Total number of records matching the request across every page, not just the current one. null on an uncounted list; page using has_next. A relevance-ranked search is uncounted, and a searched events list stays uncounted even with sort. A searched markets list with sort returns a total over the ranked matches (at most 10,000).

The 1-based page number this response covers.

Maximum number of items on a page. The last page may hold fewer.

Total number of pages available at the current per_page. null whenever total is null; page using has_next.

True when a page exists after this one.

True when this is not the first page.

True when total and total_pages reflect the server's counting ceiling rather than the exact matched count: the real set is at least total large. Render such totals as a lower bound (for example "10,000+"). Omitted when the count is exact. A sorted markets search that fills the 10,000-candidate ceiling sets this flag.
