CDXGeoStream is our flagship location intelligence service. It brings together the capabilities of CDXZipStream and CDXGeodata in one service that works in the spreadsheet you already use, in your own code, and in conversation with Claude. No installation is needed to get started.
Geocoding
Rooftop-accurate geocoding worldwide, plus reverse geocoding from coordinates to the nearest address.
Travel distance, time and directions
Driving distance and duration with turn-by-turn directions, real-time traffic, walking and transit.
Distance and radius
Straight-line distances between ZIP Codes or coordinates, every ZIP Code within a radius, and nearest locations.
Demographics
American Community Survey and Census data covering income, age, education, housing value and more.
Geographic access analysis
Find the closest facilities, stores or service locations, with templates for network adequacy and site location.
Address accuracy
Standardize address lists to USPS format with ZIP+4, and parse addresses into their parts.
ZIP Code lookup
ZIP Codes for an address, ZIP Code lists by city, county or state, and county-to-ZIP lookups.
Mapping and route optimization
Road or aerial maps right in the worksheet, and optimized driving routes with directions.
Why drive time matters
Straight-line distance is quick to calculate, but customers travel on roads. CDXGeoStream gives you both, so you can screen with distance and decide with drive time.
