QuickSearch API: Features and Benefits in Detail

QuickSearch is a high-performance and scalable API based on up-to-date web and database technology. A major benefit of the API is that different data sources can be integrated and it can be adapted for the specific requirements of the customer. The API should leave nothing to be desired when searching for addresses.

Efficient Data Acquisition and Always Correct Addresses

When entering addresses – for example when new customer addresses are created in a CRM – errors often occur. The addresses are incomplete, typing errors creep in and the addresses are saved in a different order. All of this leads to an unsightly mess of address data, which causes more trouble and frustration. If QuickSearch is integrated, this can never happen again. 

  • While typing their search, the user is provided with accurate mailing addresses that can simply be selected.
  • The accurate mailing addresses are saved in your databases and assigned the correct XY coordinates.
  • Making the address acquisition uniform across the different channels of your business (online, telephone, intranet, etc.) reduces errors and costs.

Address Data and Coordinates

QuickSearch not only provides correct addresses, but also coordinates. This is very convenient.

Up-to-date and Comprehensive Address Data for 70 Countries

Address data are available for 70 countries in Europe and America. WIGeoGIS optimizes the structure and content for the API, and in a further step integrates the data in the search database. The QuickSearch API is generally able to provide exact WGS 84 coordinates for street addresses. The address data is updated every year and is therefore always up to date.

    • external services (e.g. Quicksearch API)



  • How efficient is the search with large data sets?

    QuickSearch is optimized for high-performance queries in large address databases. Response times are typically in the millisecond range, even with parallel queries. Scaling is possible across common server and cloud architectures.

  • How can QuickSearch be integrated?

    QuickSearch is available as a REST API and can be easily integrated into web applications, GIS, CRM systems, and databases. The integration is done via HTTPS endpoints with JSON responses.

  • What is the difference between QuickSearch API and JoinAddress API and how are they related?

    QuickSearch is a module of the JoinAddress API. While QuickSearch was developed for interactive and error-tolerant address searches with autocompletion (typeahead), JoinAddress, as a more comprehensive geocoding API, offers additional features such as batch geocoding, reverse geocoding, and validation of large address databases. Both modules can be used individually or in combination, depending on the use case and integration requirem
