November 2024 Update: Great News! The API is enabled again! Plus an updated site is just around the corner!

First we would like to thank all our loyal users, especially the ones who have donated!

Since we have been subject to abuse of our API from several large companies and smart phone app creators who have incorrectly implemented our API, we have essentially been DDoSed for the past few months. (and our SSL cert expiring *doh*)

We have tested the new site a few times during off-peak hours and the results are extremely promising! If you would like to help test our beta site, please Contact Us and let us know you are interested in the beta. We will get back to you with a link when the beta is live.

Our current site will continue to operate without the API enabled and once the beta site goes live, all (correct) API queries will be backward compatible with the new website.

Please feel free to contact us via our Contact Us page with any questions, improvements, requests, ideas, or anything at all you may have.

Especially if you have any improvements or feature requests for the new site, we will accomidate and pack as many features as we can into the new site before it goes live!

Thank you!
