Marginalen Bank API Access | open-banking.io

Pull your Marginalen Bank data into any app without wrestling with bank-specific SDKs or eIDAS certificates. open-banking.io gives you a single, standards-based gateway to Marginalen Bank (BIC MARGSESSXXX) and 2,600+ other banks across the EU and UK, so a Swedish personal account behaves the same in your code as any other institution on the network.

Whether you're building a budgeting tool, an accounting integration, or an internal dashboard, you authenticate once and start reading live account information straight away.

What data you can access

• Accounts — identifiers, currency and metadata for personal accounts
• Balances — up-to-date booked and available balances
• Transactions — historical and recent movement history for reconciliation and categorisation

Consent and coverage

Marginalen Bank supports personal account types through open-banking.io. Each customer authorisation is valid for a maximum consent window of 180 days, after which the user simply re-confirms access. Coverage runs through the same PSD2 rails Marginalen Bank exposes to licensed third parties.

Privacy by design

open-banking.io is zero-knowledge and certificate-free. You don't provision or maintain QWAC/QSEAL certificates, and we don't retain your users' banking credentials. Data flows through, not into a permanent store — keeping your compliance surface small.

Pricing

One flat plan of roughly EUR 3/month covers Marginalen Bank alongside every other bank on the network. No per-connection fees, no enterprise onboarding.
