Thank you Fanny!
We source data from the lion.gdb (geo-database) for this.
We are currently finding ways to implement GST as a proper/more mature API so that any “app” can call the results ( we plan to encode in geojson ) seamlessly into their application through simple HTTP requests.
Open to suggestions here.
For the time being you can issue curl requests from the command to get the GST result.
curl -s ‘http://geostreettalk.city:5000/coordinate/?40.743074,-73.996391' | grep h1
