Harnessing the Power of GeoGeneral: CDXGeoData’s Core Location Lookup API

Overview

GeoGeneral is the foundational lookup endpoint of the CDXGeoData suite, returning city, county (or province), state, latitude, and longitude given a U.S. ZIP Code or Canadian postal code.

It supports both U.S. and Canadian coverage via separate REST endpoints (/api/geogeneral and /api/geocanadiangeneral).

Each request is token‑based—responses include a TokenCharge field, and you receive 100 free tokens to get started.

Flexible output formats (JSON, XML, CSV) make it easy to plug into everything from web apps to batch workflows.

Beyond GeoGeneral, CDXGeoData offers a full suite of services including GeoRadius, GeoDistance, GeoDemographics, and more.

Key Business Use Cases

1. Intelligent Store & Service‑Area Mapping

• Highlight nearby outlets on customer check‑out pages.
• Auto‑route orders to the closest fulfillment center.
• Visualize catchment areas for new store site planning.

2. Geospatial Data Enrichment for Analytics

• Segment customers by county or MSA for targeted campaigns.
• Aggregate sales metrics across regions for dashboards.

3. Regulatory & Compliance Workflows

• Apply correct tax rates or licensing rules.
• Route requests to the proper regional team.
• Ensure adherence to data‑residency requirements.

            var url = $"https://geodata.cdxtech.com/api/geogeneral?key={apiKey}&postalcode={postalCode}&format=json";

            using var client = new HttpClient();
            var response = await client.GetAsync(url);
            response.EnsureSuccessStatusCode();

            var json = await response.Content.ReadAsStringAsync();
            var data = JsonSerializer.Deserialize(json);
            Console.WriteLine($"City: {data.GetProperty("City").GetString()}");
            Console.WriteLine($"State: {data.GetProperty("State").GetString()}");
            Console.WriteLine($"Lat/Long: {data.GetProperty("Latitude")}, {data.GetProperty("Longitude")}");
        }
    }
}

Getting Started

1. Grab your free API key (100 tokens) from the GeoData portal.
2. Choose your format—JSON for apps, CSV for bulk workflows.
3. Plug in & go with a single HTTP call—no callbacks, no pagination, no fuss.

Pro Tip: For rooftop‑level precision, try the GeoCodeGoogleSingle endpoint powered by Google Maps.
