500px is an online community for photographers and fans of photography. Photographers can upload their pictures to share with other 500px users, and all users can browse and search the photo collection for discovery and artistic inspiration. The 500px API allows developers to access and integrate the functionality and content of 500px. Some example API methods include searching and retrieving photos, uploading photos, and finding users.
This week, 500px cryptically announced the 500px API would no longer be available for free. The announcement hints that the API will continue to be available for a price, but no pricing tiers or models have been published. The announcement was made via Hacker News and developers are speculating.
