I'm building an app using a free Switzerland API (no auth needed).

API: GeoAdmin ~ Swiss geodata, search & maps (swisstopo)
Provider: Federal Office of Topography (swisstopo)
Endpoint: GET https://api3.geo.admin.ch/rest/services/
It returns JSON (live data).

Source: Federal Office of Topography (swisstopo) (https://api3.geo.admin.ch/services/sdiservices.html)
Source type: Official public feed
Endpoint type: Public feed, non-JSON
Integration difficulty: Copy-paste ready
Last checked: 2026-07-05
Production caveat: Still handle downtime, changing fields, empty responses, and rate limits before shipping user-facing alerts.

Help me fetch this and build a simple page that displays it nicely. Include basic production safeguards for errors, empty responses, schema changes, caching, and rate limits.
