OpenUV

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.

OpenUV publishes 3 APIs on the APIs.io network: Account API, Protection API, and UV Index API. Tagged areas include Weather, UV Index, Sun, Solar, and Geolocation.

The OpenUV catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

OpenUV’s developer surface includes authentication, developer portal, developer console, signup flow, pricing, support, engineering blog, and 17 more developer resources.
