Copernicus near-realtime CAMS T and RH for free? : meteorology

Hello,

before anyone point it out I know values on subject are freely available.

What I am seeking is a cloud service offering API access to just T and RH, of multiple POI on landmasses, 2m AGL, near-realtime, about 30 times a day. Multiple POI means 10 for now. Can become many more. Non-for-profit, open source cloud service of mine I want to expand a little.

Looked at some weather data services found by rapidapi, DIAS for Copernicus and by Copernicus itself. They offer too much and as such charge too much for my nimble needs. I am sure somebody is already mirroring CAMS data and decoding the latest available GRIB bi-daily. Please get in touch. Thanks.
