**APIs profiled:** 7

Atomic is the connected-banking infrastructure for income, payroll, and merchant data. Their user-permissioned APIs let banks, lenders, fintechs, and HR platforms link consumers to thousands of payroll providers, gig platforms, employers, and merchants — and then read or update that data in real time. Core use cases include direct-deposit switching, paycheck-linked income and employment verification, tax-document retrieval, and card-on-file / subscription management. Integration is done through the Transact SDK (web, iOS, Android, React Native, Flutter, Capacitor) plus a REST API at api.atomicfi.com that manages access tokens, tasks, companies, deposit accounts, and webhooks. Atomic is headquartered in Salt Lake City, Utah.
