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

API: OpenPLZ ~ DACH postal codes, places & streets
Provider: OpenPLZ API (OpenPotato)
Endpoint: GET https://openplzapi.org/
It returns JSON.

Source: OpenPLZ API (OpenPotato) (https://www.openplzapi.org/en/)
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.
