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

API: National Weather Service ~ US weather API
Provider: National Weather Service (NOAA)
Endpoint: GET https://api.weather.gov/
It returns JSON (live data).

Source: National Weather Service (NOAA) (https://www.weather.gov/documentation/services-web-api)
Source type: Official public feed
Endpoint type: Direct public JSON endpoint
Integration difficulty: Copy-paste ready
Last checked: 2026-07-05
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.
