This is Brave's autocomplete API packaged as a skill. It's built for sub-100ms responses, so you can wire it directly into search-as-you-type UIs with a 150-300ms debounce. The basic mode just returns query suggestions, but flip on rich mode and you get entity data with titles, descriptions, and images, which is great for preview cards. It handles typos without needing a separate spellcheck pass. The main gotcha is that rich suggestions require a paid Brave Search plan on top of the Suggest plan. If you're building any kind of search interface or need to clean up ambiguous queries before hitting a RAG pipeline, this does exactly that job without reinventing the wheel.
