US Zipcode, County, City, and State Boundaries API:
A simple & very fast API that will allow you to integrate multiple GeoJson US boundaries results into your apps and systems.
This API is designed to be used programatically for optimal performance. When using the MashApe UI for queries expect significant latency issues on large result sets!
We use 2016, 2017 and 2018 US Census/TIGER data from the United States Government and other data sources to populate our repositories.
Our infrastructure consists of multiple servers across the united states in the cloud, so we guarantee 99.9% up time while using our service.
Test the API
Copy and paste the results here: http://geojsonlint.com to see a sample of how it would look on a browser that accepts GeoJson( GoogleMaps,Open layers,etc.). This API is designed to be used programatically for optimal performance.
