Consent and coverage

Both personal and business account types are covered. open-banking.io reaches 2,600+ banks across the EU and UK, so adding neighbouring Sparkassen or cross-border institutions later is just another API call — no new contracts.

Privacy by design

open-banking.io is zero-knowledge: banking credentials go directly to Sparkasse Westmünsterland during SCA and are never stored or seen by us. There are no eIDAS/QWAC certificates to buy or renew — the platform handles regulatory access on your behalf, so you ship faster and stay compliant.

Pricing

Flat, predictable pricing from ~EUR 3/month — no per-call surcharges and no setup fees, so you can prototype and scale on the same plan.
