Unified API Access

Register once and get instant access to every dataset on the platform. No per-source registration, no bureaucracy.

Single API token

One token to access Swissmedic, Zefix, SECO and all future datasets

Consistent format

Same REST conventions, same pagination, same filtering across all endpoints

New datasets automatically

When we add new data sources, your token works immediately - no re-registration needed

Why OpenData Altius?

Swiss public data exists but is often locked behind complex registration processes or inaccessible formats. We fix that.

No Registration Hassle

Some official APIs require months-long registration processes. We handle the complexity so you don't have to.

RESTful APIs

Clean, documented REST APIs with search, filtering, pagination. Export in JSON, CSV and more.

Regularly Updated

Data is imported from official Swiss sources and kept up to date. LINDAS, Swissmedic and more.
