Teller is a US banking API providing direct connections to bank accounts with instant data access, balance checks, and payment initiation without screen scraping.
About
Teller is a US-focused banking API that gives developers direct, real-time access to bank account data and payment initiation without relying on screen scraping or batch-updated aggregation services. Unlike legacy financial data aggregators that use credential-based scraping and update account data nightly, Teller establishes direct connections to major US financial institutions and retrieves live transaction and balance data. This approach results in higher data quality, faster refresh rates, and more reliable connections that do not break when banks update their web interfaces.
