About Teller
What is Teller?
Teller is an API that lets your application instantly connect to users' bank accounts, giving you access to account ownership, ACH details, balances, transactions, and identity data. It replaces brittle, error-prone bank connections with a stable, real-time interface.
Who is it for?
Teller is built for fintech developers, payment platforms, budgeting apps, lending services, and any SaaS that needs to verify bank accounts or pull financial data. It is not intended for individual consumers or non-technical users; it requires integration via its API or SDKs.
Key capabilities
With Teller you can verify account ownership and ACH details, check live balances before debits, view full transaction histories, confirm customer identity, and initiate payments via Zelle. The platform supports over 7,000 financial institutions and offers a zero-code migration path from Plaid.
Real use cases
Lenders use Teller to pre-validate accounts and underwrite loans with live balance data. Payment platforms verify ACH routing numbers before processing debits. Personal finance apps sync transactions automatically, reducing manual entry and support tickets.
