What data you can access

• Accounts — identifiers and metadata for both personal and business accounts.
• Balances — current and available figures, refreshed on demand.
• Transactions — booked and pending entries with counterparties, amounts and references.

Consent and coverage

Sparkasse Duderstadt supports a maximum consent window of 180 days, after which the account holder simply re-authorises to keep the connection active. Both business and personal account types are covered. Beyond this one bank, open-banking.io reaches 2,600+ banks across the EU and UK — so the same code that reads Sparkasse Duderstadt scales to the rest of your portfolio.

Privacy by design

The platform is zero-knowledge: credentials are entered only on the bank's own screens, and open-banking.io never stores login secrets. Because the connection is certificate-free, you skip the costly QWAC/QSEAL setup that traditional PSD2 access demands, while consent stays fully in the account holder's hands.

Pricing

Access starts at roughly EUR 3 per month — a flat, predictable cost with no certificate fees or per-call surprises.
