Radius Reports API - How It Works

The API takes a user-provided latitude and longitude and returns demographics, population projections and geojson for 1, 3 and 5 mile buffers around the supplied point.

Making a request for a Radius Report

All requests are POST requests with a JSON body and an Authorization Token header.


Example Call in curl

curl -X POST \
  -H "Authorization: Token API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"radius_report": {"latitude": 32.361538, "longitude": -86.279118}}' \

Requesting an API Key

Send a request to help@cubitplanning.com. The only requirement is a contact email address.  We will generate the key and send it to you at the provided address.
