Welcome to the PurpleAir API PurpleAir was founded on principles of openness, sharing, and community. It is to strengthen these principles and ensure the success of our entire community that we put together updated terms of service, data license, and data attribution requirements when using PurpleAir data and this API. Please take a moment to review them and note the attribution guide and data license agreement. If you have any questions or need more information, we have an excellent resource at https://community.purpleair.com/c/data/api/.
