Banking primitives — accounts, ACH, wires, and cards — exposed as a direct API.

Visit website

Overview


Increase exposes banking primitives as a direct API: ACH, wires, real-time payments, cheques, card issuing, and a real-time ledger.

The API is the primary interface rather than a dashboard, and the sandbox reproduces production semantics including settlement timing and return codes. Transaction records are immutable and bookkeeping primitives are built into the data model.

Common use cases


  • Send an ACH or wire from application code
  • Hold funds in a programmatically managed account
  • Issue cards with spend controls
  • Test money movement in a sandbox that mirrors production

Key Features


  • Direct API access to ACH, wires, RTP, and cheques
  • Real-time ledger with immutable transaction records
  • Card issuing with programmatic controls
  • Sandbox that mirrors production semantics
  • Bookkeeping primitives built into the API
  • Designed for engineers rather than a dashboard UI
