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

API: API Géo ~ French communes, EPCI & regions
Provider: Etalab / DINUM
Endpoint: GET https://geo.api.gouv.fr
It returns JSON.

Source: Etalab / DINUM (https://geo.api.gouv.fr/decoupage-administratif)
Source type: Official open-data catalogue
Endpoint type: Open-data catalogue JSON
Integration difficulty: Copy-paste ready
Last checked: 2026-07-05
Production caveat: Still handle empty rows, schema changes, pagination, stale coverage, and temporary upstream failures.

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.
