Mediobanca Premier API Access & Open Banking Data

Pull your Mediobanca Premier balances and transaction history into one place with open-banking.io, a certificate-free PSD2 aggregation service covering 2,600+ European banks. Mediobanca Premier — the Italian retail arm formerly known as CheBanca! — supports both business and personal accounts under BIC MICSITM1XXX. Because open-banking.io is zero-knowledge, your financial data is decrypted only on your own device with a key that never leaves it, so no one else (not even us) can read it.

How to connect Mediobanca Premier

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

  1. Sign up for open-banking.io and open the web dashboard.
  2. Set an encryption passphrase. Your key pair is generated locally on your device; our servers only ever hold your public key.
  3. Pick Mediobanca Premier from the bank list and choose your account type (business or personal).
  4. You are redirected to Mediobanca Premier's own secure login, where you approve access (standard PSD2 consent).
  5. Your accounts sync back into the dashboard automatically.

Note that Mediobanca Premier grants a 7-day maximum consent window, so you'll re-approve access on their login screen roughly once a week to keep the sync live.

Access your data

Once a connection exists, developers can optionally read it 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 directly. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own returns only ciphertext — without your private key the data stays unreadable, which is what makes the whole pipeline zero-knowledge. The CLI and SDK only read or refresh connections that already exist; they never create one.

All of this runs at roughly EUR 3/month, with no certificates or eIDAS setup to manage.

Do I need a developer account to use Mediobanca Premier?

No. Connecting and viewing accounts works entirely in the dashboard. API keys are only for programmatic reads.

Why do I reconnect Mediobanca Premier so often?

Mediobanca Premier caps consent at 7 days, so periodic re-approval on their login is required by their PSD2 policy.

Can open-banking.io see my Mediobanca Premier data?

No. Data is encrypted with your device-held key; our servers store only your public key and encrypted blobs.
