This API is free to use for anyone creating Animal Crossing: New Horizons apps / websites / communities. The only requirement to use this API is to include a link back here to give credit back to Aeon and DodoCodes.com for making this possible.
Available endpoints for your apps to use. Please note that these APIs are currently a work in progress and may include breaking changes in the future. Let us know which of these seem useful and we'll remove the extras.
