@Danil-Utiuzh I discussed this with colleagues from the product team and there was no change according to our API in the last months. Also if you take these data officially from our API with paid Professional license, there shouldn't be any problem. We provide everything mentioned in our documentation in our API.
If there is any error on your end and you think it is the problem of Windy, we can help you, but we need to check your publicly accessible project. Without that, we are not able to assist.
