Landesbank Saar API Access & Open Banking Data

Landesbank Saar (SaarLB) is the state bank of Saarland, serving business and personal customers across the German-French border region. If you want your Landesbank Saar balances and transactions in one place — or feeding your own tooling — open-banking.io gives you PSD2 access without certificates, eIDAS setup, or the usual regulatory paperwork. It covers 2,600+ EU and UK banks, and everything is decrypted locally with a key that never leaves your device.

The service is zero-knowledge by design: open-banking.io holds only your public key, so its servers can never read or decrypt what syncs from your account. That certificate-free, privacy-first model costs around EUR 3/month.

How to connect Landesbank Saar

Connecting happens entirely in 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 key pair is generated right there on your own device.
  2. In the dashboard, pick Landesbank Saar (BIC SALADE55XXX) and choose your account type — business or personal are both supported.
  3. You are redirected to Landesbank Saar's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials only ever touch the bank.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once Landesbank Saar 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 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. The CLI and SDK only read and sync connections you already made in the dashboard — they never establish one.

Does open-banking.io ever see my Landesbank Saar data?

No. It is zero-knowledge and stores only your public key. Data is encrypted for you and decrypted on your device.

Can I use the API key on its own to pull readable data?

No. An API key alone returns ciphertext. Readable output requires your private key from credentials.json, which stays with you.

Which account types can I connect?

Both business and personal Landesbank Saar accounts are supported, with consent valid for up to 180 days per approval.
