I'm integrating a Norway API into my app.

Provider: Meteorologisk institutt (MET Norway)
Auth: requires an API key (sign up: https://frost.met.no/howto.html)
Pricing: free
Base URL: https://frost.met.no
Important note: Free access to quality-controlled historical observations; you register an email to get a client ID used as the request credential.

Source: Meteorologisk institutt (MET Norway) (https://frost.met.no/howto.html)
Source type: Official open-data catalogue
Endpoint type: Open-data catalogue JSON

Last checked: 2026-07-05
Production caveat: Keep credentials server-side and confirm current limits, pricing, and webhook/error behaviour in the provider docs.

Help me set up the correct onboarding/authentication path and make the first valid request ~ explain exactly where credentials go and what must happen before production.
