Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück API Access

Reading your Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück accounts programmatically usually means EU licensing, eIDAS certificates, and a PSD2 compliance stack. open-banking.io removes all of that. It is a certificate-free, zero-knowledge bridge to 2,600+ European banks, and Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück (BIC MALADE51BKS) is one of them. Your balances and transactions are decrypted on your own device with a key only you hold, so the service never sees your financial data in the clear.

Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück asks you to re-authorise.

How to connect Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück

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 key pair is generated locally on your device; open-banking.io only ever stores your public key.
  2. In the dashboard, choose Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück and select whether you are linking a business or personal account.
  3. You are redirected to Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard, and refreshed data keeps flowing until the 180-day consent expires.

Access your data

Programmatic access is an optional step you take after the account is connected. Open the Developers page, create an API key, and export a credentials.json — this file 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. Every request carries your X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key the payload stays unreadable, which is what makes the system genuinely zero-knowledge.

All of this runs at around EUR 3/month, with no certificate procurement and no per-connection licensing.

Do I need an eIDAS certificate?

No. open-banking.io handles the regulated PSD2 layer, so you connect Sparkasse Mittelmosel-Eifel-Mosel-Hunsrück without any certificate of your own.

Can open-banking.io read my transactions?

No. It holds only your public key. Data is encrypted for you and decrypted on your device, so the servers only ever store ciphertext.

Can I connect an account with the CLI or SDK?

No. Connecting is done in the dashboard against the bank's consent screen. The CLI, SDK, and API only read and sync accounts you have already linked.
