  description: Anything that you can achieve with PDFs, presence, and persistence in a bank branch you can do with our API. We've always wanted a fully programmatic bank so we built one. Our API faithfully exposes the data and capabilities of the Federal Reserve, Visa, The Clearing House, depository networks, and accounting tools. It's lovingly boring and exceptionally powerful. If you have any questions or want to get started, don't hesitate to ping us at sales@increase.com. We can't wait to see what you build!

      description: You can use this API to confirm if a routing number is valid, such as when a user is providing you with bank account details. Since routing numbers uniquely identify a bank, this will always return 0 or 1 entry. In Sandbox, only a few [routing numbers are valid](/documentation/sandbox-test-values#routing-numbers). `110000000` is an example of a Sandbox routing number.
