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

Provider: National Environment Agency
Endpoint: GET https://data.gov.sg/api/action/datastore_search?resource_id=d_b4cf557f8750260d229c49fd768e11ed&limit=10
It returns JSON.

Source: National Environment Agency via data.gov.sg (https://data.gov.sg/datasets/d_b4cf557f8750260d229c49fd768e11ed/view)
Source type: Official open-data catalogue
Endpoint type: Open-data catalogue JSON
Integration difficulty: Copy-paste ready
Last checked: 2026-06-29
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.
