The Problem

Why generic solutions fall short

Swiss developers face unique challenges when validating addresses.

Unsuitable generic APIs

Google Maps and other global services don't understand Swiss specifics: multiple postal codes, merged municipalities, bilingual formats, precise postal rules.

Unpredictable costs

Volume-based pricing from major APIs quickly explodes. Impossible to budget confidently for e-commerce or high-traffic applications.

Complex Swiss rules

4 national languages, cantons with their own conventions, local abbreviations, variable address formats... A real headache to manage yourself.

The Solution

A specialized API that truly understands Swiss addresses.

100% Swiss-focused

Predictable pricing
