Highlight API
Highlight search terms in text. The highlight endpoint wraps every match of one or more terms in a marker — defaulting to <mark>…</mark>, or any open/close strings you choose (** for Markdown, ANSI codes for the terminal, a CSS span, anything) — and returns the marked-up text and a match count. The snippets endpoint returns short excerpts of the surrounding context around each match, the way a search-results page shows where your query appears. Matching is case-insensitive by default with optional whole-word mode, and terms are matched literally (regex characters are safely escaped). Perfect for search results and in-page find, keyword spotting, log review and document previews. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from search, summarization and diff APIs.
