Caja Rural de Asturias API Access & Open Banking

Caja Rural de Asturias (BIC BCOEESMM059) is part of Spain's Grupo Caja Rural network, serving households and businesses across Asturias. With open-banking.io you can reach your Caja Rural de Asturias balances and transactions through a single PSD2-compliant service — no bank certificates, no eIDAS setup, and no code required to get started.

What makes open-banking.io different is where the decryption happens. When you create your account you set an encryption passphrase, and the keys derived from it are generated on your own device. open-banking.io only ever holds your public key, so the servers physically cannot read or decrypt your Caja Rural de Asturias data. It stays ciphertext everywhere except on your machine.

How to connect Caja Rural de Asturias

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, key, or redirect to wire up yourself.

1. Sign up for open-banking.io and set your encryption passphrase (your private key is created locally, right there in the browser).
2. In the dashboard, search for and select Caja Rural de Asturias, then choose the account type you want to link — business or personal.
3. You are redirected to Caja Rural de Asturias's own secure login, where you approve access on the bank's official consent screen.
4. Control returns to the dashboard and your accounts begin syncing. The PSD2 consent stays valid for up to 180 days, after which you simply re-approve.

That's the whole flow — you authenticate directly with the bank, and open-banking.io never sees your credentials.

Access your data

Once the connection exists, developers can optionally read it programmatically. Open 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. Without that private key an API key alone returns only ciphertext. Note the CLI and SDK read and sync existing connections — they never establish new ones.

All of this runs for around EUR 3/month, covering 2,600+ EU and UK banks.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — the dashboard consent flow handles PSD2 authorization for you.

Can open-banking.io see my Caja Rural de Asturias transactions?

No. It stores only your public key, so data is decrypted solely on your device.

How long does access last?

Up to 180 days per consent, then you re-approve on the bank's screen.
