**APIs profiled:** 3

OpenUV provides a global real-time UV index API. The service combines meteorological inputs (ozone, cloud cover, area reflection) with NASA satellite sources to return current UV index, daily maximum UV, ozone level, safe sun-exposure times per Fitzpatrick skin type, and a recommended sun protection window for any geographic coordinate.
