Hello! As i can see API is already exists

Example: https://www.lightpollutionmap.info/QueryRaster/?qk=MTY1MjYxNTk5MjI5NTtpc3Vja2RpY2tzOik=&ql=viirs_2021&qt=point_t&qd=48.74783729168823,55.75136844953553 where qk is API Key (i think you can just use key from their website), ql is data layer (2021 is the latest data available) and qd is a coordinates (obviously)

Response format is pretty simple - before the comma there is a list of measurements (starting from 2012 to 2021) separated by semicolon. After a comma there is a elevation in meters (no idea why it needed)
Example: 0.8;1.7;7.6;26.4;40.8;43.9;46.1;42.9;39.4;52.9,205)
