Consent and coverage

American Express (France) supports both business and personal accounts. A single authorization stays valid for up to 180 days before the cardholder simply re-approves — one of the longest consent windows available, meaning fewer interruptions for your users.

Privacy by design

open-banking.io is zero-knowledge: we never see or store your customers' banking credentials, and there are no eIDAS certificates to buy, install, or renew. Authentication happens directly with American Express, and you hold the access tokens. Less compliance overhead, less risk.

Pricing

Flat, predictable access from around EUR 3/month — no per-call surcharges and no certificate costs. Connect American Express and thousands of other banks under one simple plan.
