# Ultra to Meta-Aggregator

> Migrate from Ultra /order + /execute to Swap V2

If you currently use Ultra `/order` + `/execute`, migration is minimal. The endpoints are the same, with a new base URL.

## What changes

| Before (Ultra) | After (Swap V2) |
| - | - |
| Base URL: `https://ultra-api.jup.ag` | Base URL: `https://api.jup.ag/swap/v2` |
| `GET /order` | `GET /order` |
| `POST /execute` | `POST /execute` |

The request parameters and response format are identical. Update the base URL and you are done.

## What you gain

* Unified documentation and API reference
* Same endpoint for both Meta-Aggregator and Router paths
* Future improvements shipped to V2 first
