Unit
Unit is a Banking-as-a-Service (BaaS) platform that lets companies embed deposit accounts, cards, payments, and lending into their own products without becoming a bank. A single REST API, built on the JSON:API specification (media type application/vnd.api+json) and secured with Bearer/JWT tokens, covers onboarding (Applications), Customers, Deposit and Credit Accounts, Debit and Credit Cards, real-time card Authorizations, Payments (Book, ACH, Wire, Recurring, Cash Deposits), Counterparties, Checks, Transactions, Statements, Tax Forms, Fees, Rewards, Credit and Repayments, and Events delivered as signed HTTP webhooks. Unit publishes an official OpenAPI 3.0.2 specification (github.com/unit-finance/openapi-unit-sdk) plus generated Node.js, Python, Ruby, and Java SDKs. Sandbox runs at api.s.unit.sh; production access is provisioned per signed BaaS agreement with Unit's partner banks.
Unit publishes 17 APIs on the APIs.io network, including Accounts API, API Tokens API, Applications API, and 14 more. Tagged areas include Fintech, Backend-as-a-Service, Banking, Payments, and Card Issuing.
The Unit catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Unit’s developer surface includes authentication, documentation, engineering blog, API reference, getting-started guide, signup flow, sandbox, and 35 more developer resources.
