# Execute Service

```
POST https://api.soul.mds.markets/v1/soul/{slug}/services/{service}/execute
```

Executes a service with x402 payment. The first call returns a quote; the second call, with payment, runs the service.

## Path Parameters

| Parameter | Type   | Description  |
| --------- | ------ | ------------ |
| `slug`    | string | Soul's slug  |
| `service` | string | Service slug |

## Headers

| Header       | Required     | Description                                     |
