Spellcheck

This is Brave's standalone spellcheck endpoint, mainly useful when you need to validate or correct a query before deciding what to do with it. Most of the time you won't need it since Brave's web search already has spellcheck baked in by default. The sweet spot is building "did you mean?" UI flows or cleaning up queries before routing them to different services. It handles context aware corrections (so "artifical inteligence" becomes "artificial intelligence") and supports 51 language codes. The response is dead simple: you get back an array of corrected suggestions, or an empty array if nothing needs fixing. Think of it as a preprocessing step, not your main search tool.
