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

API: Marktstammdatenregister ~ energy unit registry
Provider: Bundesnetzagentur (BNetzA)
Endpoint: GET https://api.data.gov.my/data-catalogue/?id=de-marktstammdaten-energy&limit=10&sort=-date
It returns JSON.

Source: Bundesnetzagentur (BNetzA) (https://www.marktstammdatenregister.de/MaStR/Datendownload)
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.
