What data you can access

• Accounts — identifiers and metadata for business and personal accounts
• Balances — current and available amounts, refreshed on demand
• Transactions — dated, categorised entries with counterparty details

Everything arrives in one consistent JSON schema, so the code you write for Basisbank works unchanged across all 2,600+ connected banks.

Consent & coverage

Basisbank consent lasts up to 180 days before your user needs to re-authorise. The connection covers both business and personal account types. No BIC is required to route requests — open-banking.io resolves the institution for you.

Privacy by design

The platform is zero-knowledge: credentials go straight to Basisbank and are never stored on our side. Access is certificate-free, so there are no eIDAS QWACs or QSEALs to buy, renew or manage. You hold the keys; we simply move the data.

Pricing

Flat, predictable pricing at around EUR 3/month — no per-call surcharges and no setup fees. Scale from a single account to a full portfolio without repricing.
