Public APIs

At AVAIL we are vociferous consumers of Open Data and we love using API's. We create API's to extend the utility & value of Open Data.


Based on the work of GTFS Data Exchange, this API allows direct access to GTFS feeds for hundreds of transit agencies. It extends GTFS by adding route & stop geography (GeoJSON & TopoJSON), as well as a number of analytic data (eg. route headway, stop wait times).

Tired of processing geography files by hand for each new mapping project? We were, so we created this API to make adding census geographies to any project easier.


  1. States, Counties, Congressional Districs, Tracts and Block Groups
  2. Get data as GeoJSON or TopoJJON
  3. Ingelligent Polygon Simplification for Large Datasets
  4. Add SF1 & ACS variables from
