Lunar Norway Open Banking & API Access Explained

Reaching your Lunar account data no longer means wrestling with bank certificates or bespoke PSD2 onboarding. open-banking.io gives you a single, privacy-first route to Norwegian Lunar accounts — both business and personal — and turns them into data you can actually use. Lunar operates on BIC LUNADK22XXX, and a single authorisation keeps your access live for up to 180 days before you renew.

The service is certificate-free and zero-knowledge: encryption keys are generated on your own device, and open-banking.io only ever holds your public key. Nothing on their servers can read or decrypt your Lunar transactions — that happens locally, under a key only you control.

How to connect Lunar

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase; your keys are created on your device at this moment.
  2. Open the dashboard and choose Lunar from the bank list, then pick the account type — business or personal.
  3. You are redirected to Lunar's own secure login, where you approve access under PSD2 (valid for up to 180 days).
  4. Your Lunar accounts then sync back into your dashboard, ready to view.

Access your data

Once Lunar is connected, reading the data programmatically is an optional developer step. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key, the data stays sealed.

All of this runs at roughly EUR 3/month, covering 2,600+ EU and UK banks with no per-bank setup fees.

Do I need an API key to connect Lunar?

No. Connecting is done in the dashboard via Lunar's own consent screen. API keys only matter later, if you want to read data programmatically.

Can open-banking.io see my Lunar transactions?

No. It is zero-knowledge and holds only your public key; decryption happens on your device with a key only you have.

How long does my Lunar access last?

Up to 180 days per authorisation, after which you re-approve on Lunar's login screen.
