Julius Baer (Luxembourg) API Access & Open Banking

Julius Baer's Luxembourg arm (BIC BAERLULU) serves private-banking and corporate clients across the Grand Duchy. If you want your own balances and transactions in one place — a spreadsheet, a dashboard, or a script — open-banking.io gives you PSD2 access to Julius Baer without certificates, sandboxes, or a developer contract with the bank. Both business and personal accounts are supported, and a single approval keeps data flowing for up to 180 days before you re-confirm.

Everything is decrypted on your own machine with a key only you hold, so open-banking.io never sees your Julius Baer data in the clear.

How to connect Julius Baer

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

  1. Sign up at open-banking.io and set an encryption passphrase. Your keys are generated locally on your device.
  2. In the dashboard, search for Julius Baer (Luxembourg) and choose the account type — business or personal.
  3. You're redirected to Julius Baer's own secure login, where you authenticate and approve access (standard PSD2 consent).
  4. Control returns to your dashboard, and your Julius Baer accounts sync in automatically.

That's it — no paperwork, no eIDAS certificate, and nothing to install to get started.

Access your data

Once Julius Baer is connected, developers can optionally read the data programmatically. On 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:

  • CLI: openbanking accounts, openbanking transactions, openbanking sync
  • SDK or the REST API for your own integrations

Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your key. The API key alone only ever returns ciphertext — without your private key, no one (including open-banking.io) can read it. Note that the CLI and SDK only read and sync connections you've already made in the dashboard; there is no connect command.

All of this runs for roughly EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — you approve access directly on Julius Baer's login screen.

Can open-banking.io see my Julius Baer balances?

No. It's zero-knowledge and stores only your public key; data is decrypted on your device.

No. Julius Baer consent runs up to 180 days, after which you re-approve access.
