  title: Increase API
  description: >-
    Increase is a bank-grade payments and financial infrastructure platform that
    exposes a single REST API for moving and holding money in the United States.
    This document models the primary resources of the Increase API - Accounts,
    Account Numbers, Cards, Card Payments, ACH / Wire / Real-Time Payments / Check
    transfers, Transactions, Entities, Events and webhooks, Bookkeeping, Card
    Profiles and Digital Wallets, Lockboxes, and Simulations. It is grounded in
    Increase's public OpenAPI 3.1 spec (https://api.increase.com/openapi.json) and
    the Stainless-generated SDKs. Authentication is a Bearer API key. All endpoints
    are HTTPS REST; state changes are delivered as Events over HTTP webhooks (no
    WebSocket surface). Requests support idempotency via the `Idempotency-Key`
    header. This is a representative, not exhaustive, subset of the full API.
