Østre Agder Sparebank API Access & Open Banking

Østre Agder Sparebank customers can reach their account and transaction data through open-banking.io, a certificate-free service covering 2,600+ banks across the EU and UK. Instead of building your own PSD2 integration, you authorise access once and open-banking.io keeps your Østre Agder Sparebank accounts in sync. Both business and personal account types are supported, and each authorisation stays valid for up to 180 days before you renew it. Østre Agder Sparebank does not publish a BIC through this service, so none is required to get started.

The privacy model is what sets this apart. open-banking.io is zero-knowledge: your encryption keys are generated on your own device from a passphrase you choose, and the platform only ever holds your public key. Everything you retrieve is decrypted locally, so the servers store ciphertext they cannot read.

How to connect Østre Agder Sparebank

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 an open-banking.io account.
2. Set your encryption passphrase; your private key is created locally and never leaves your device.
3. In the dashboard, choose Østre Agder Sparebank and select whether you're linking a business or personal account.
4. You're redirected to Østre Agder Sparebank's own secure login, where you approve access on the bank's PSD2 consent screen.
5. Your accounts sync back into the dashboard, ready to view or export.

Access your data

Reading your data programmatically is an optional step for developers, available only after the connection above exists. On the Developers page, create an API key and export a credentials.json file — 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 alone only ever returns ciphertext.

All of this runs for roughly EUR 3 per month, with no eIDAS certificates or bank-specific paperwork to manage.

Do I need an API key to link my bank?

No. Linking Østre Agder Sparebank is done in the dashboard by approving access on the bank's consent screen. API keys only matter for optional programmatic reads afterwards.

Can open-banking.io see my Østre Agder Sparebank data?

No. The service is zero-knowledge and holds only your public key, so your data is decrypted on your device with a key only you control.

How long does access last?

Up to 180 days per authorisation, after which you re-approve access with Østre Agder Sparebank to continue syncing.
