Hi @JGielen, we’ve removed your image for privacy. However, the response indicated a PaymentRequiredError. Upon examining your API account, it looks like you were recently moved to our points based billing system. Please send an email to [contact@purpleair.com](mailto:contact@purpleair.com) and we can assist. Let us also know if any of the sensors you’re querying are purchased and we can provide points for data they’ve reported. --- _[View the full topic](https://community.purpleair.com/t/csv-file-data-readings-are-nul/7393)._
