  title: Increase Account Numbers Lockboxes 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.
