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

API: Live bus positions ~ Rapid KL & Rapid Penang (Prasarana GTFS-R)
Provider: Prasarana via data.gov.my
Endpoint: GET https://api.data.gov.my/gtfs-realtime/vehicle-position/prasarana?category=rapid-bus-kl
It returns JSON (live data).

Source: Prasarana via data.gov.my (https://api.data.gov.my/gtfs-realtime/vehicle-position/prasarana?category=rapid-bus-kl)
Source type: Official public feed
Endpoint type: Public feed, non-JSON
Integration difficulty: Copy-paste ready
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.
