Real-time UV index data and forecasts API

Overview

OpenUV API delivers real-time UV index values, hourly/daily forecasts, and sun protection window calculations. Key endpoints include /uv for current levels, /forecast/hourly for hourly trends, and /protection for safe exposure times. Responses are JSON-formatted, containing UV index, risk level (low to extreme), ozone concentration, and intensity metrics. Ideal for weather apps, skincare tools, outdoor activity planners, and health platforms to help users avoid harmful UV overexposure via location-based (lat/lng) queries.
