Early in development I had a simple API you could consume to pull the full data set. It took a few weeks of evenings and weekends, but now I have a full featured API that is way more usable than before. Now, I feel from a technical perspective there is not a lot of features missing to prevent someone from getting some use out of the site.
Next steps are to work on visibility on the web (Google) and in the developer community. I will also continue to add new data sources . Currently I have almost nobody actually seeing visiting the site.
