Use this endpoint when you need a quick, live UV index forecast keyed to a specific geographic coordinate — ideal for health apps, outdoor activity planners, or any workflow that needs to surface sun exposure risk for a user's location. Prefer this over general weather APIs when UV index is specifically the needed signal.
