Description
The REST API designed for postal code data in the United States and Canada offers various functionalities such as address validation and standardization, which includes appending ZIP+4 codes, as well as radius searches that utilize centroid haversine calculations for distances up to 500 miles and true spatial polygon intersections for distances up to 250 miles, providing a percentage of results that fall within the specified area. Additionally, it computes point-to-point distances and bearings, supports multi-entity autocomplete for cities, ZIP codes, counties, metropolitan areas, Forward Sortation Areas (FSAs), and school districts, and offers enrichments per ZIP code, including Census ACS demographic data spanning 14 years with 542 different fields, along with lookups for congressional, state legislative, and school district information. There are six available endpoints that accept various inputs such as US ZIP codes, ZIP+4 codes, Canadian FSAs, Canadian postal codes, or geographic coordinates, with the capability to batch process up to 100 entries at once. This API operates on REST/JSON over HTTPS with API key authentication, CORS support, and adheres to the OpenAPI 3 specification, complete with a public Postman collection for ease of use. Users can access a free tier allowing for 2,500 requests per day without requiring a credit card, and the service does not expire, while paid plans are available at Developer for $49 per month, Professional for $149 per month, and Business for $499 per month, with credit packs ranging from $19 to $799. The comprehensive features and flexible pricing make this API an attractive option for developers and businesses in need of postal code data and related services.
