The history of 500px has always encouraged creative development, but as of January 24th 2018, 500px will no longer be offering free access to our API. This decision was made in order to protect our assets and improve our website's performance. On June 15th, access to the API was shut down. This is part of a larger strategic shift—focusing our energy on continuing to build the world’s best photography community at 500px.com.
I have an existing key, so what does this mean for me?
If you have an existing API key, you will lose access on June 15th 2018. You can email firstname.lastname@example.org to discuss further usage of the API.
