Api Endpoint

Neural web search

Neural (embedding-based) web search over a curated web index, which finds pages by meaning rather than keyword overlap. Use it when a keyword engine returns the wrong thing: conceptual questions, 'pages like this one', or niche technical writing. Returns up to 10 results with title, URL, published date and author. Complements the keyword web search rather than replacing it.
