Overview

Teller provides a real-time bank data API for developers and businesses in fintech. It connects directly to banks via official APIs, avoiding slow, unreliable screen scraping to ensure faster, more accurate data retrieval. The product is accessed through a subscription-based API, where clients pay for a certain number of API calls per month and can scale usage as needed. Teller differentiates itself by offering direct bank integrations with high uptime and stable data, unlike competitors that rely on less stable methods. The goal is to deliver dependable, real-time banking data at scale to fintechs, financial institutions, and other businesses that need smooth integration with banking data.
