Evenhand Developers
The Evenhand REST API is the brokerage-facing programmatic surface of the Evenhand deal-management platform. It exposes the same brokerage-tenant resources that the web app does — contacts, deals, offers, diligence artifacts — over HTTPS at https://app.evenhandhq.com/api/v1.
The reference is generated from the OpenAPI 3.1 contract. The contract is the source of truth: anything not described there is not part of the API.
What's here
