# Ultra Swap API Quick Start

> Quick start guide to the Ultra Swap API: get an order, sign it, and execute.

<Warning>
  **Ultra Swap API** is no longer actively maintained and has been superseded by [Swap V2](/swap).
</Warning>

Ultra Swap uses a two-step flow: first call `GET /ultra/v1/order` to receive a base64-encoded unsigned transaction, then sign it and submit via `POST /ultra/v1/execute`. This page lists all Ultra endpoints and guides.

## FAQ

**Frequently asked questions:** Integrator fees are 5–10 bps (you keep 80%), Ultra transactions cannot be modified, and rate limits scale dynamically with swap volume.

  <Accordion title="Can I add custom integrator fees to Ultra Swap API?">
    * **Integrator without custom fees**: Do note that when your users swap using Ultra Swap, we take 5 to 10 bps of the swap amount as a fee.
    * **Integrator with custom fees**: If you are an integrator, you can add custom integrator fees via Ultra Swap API and Jupiter will take 20% of the integrator fees. Please refer to the [Add Fees To Ultra Swap](/ultra/add-fees-to-ultra) guide for more information.
