# Resolve Code Owner

> The address that owns a referral code.

### Endpoint

`GET /api/referrals/code/{code}/address`

The address that owns a referral code.

### Parameters

| Parameter | Location | Required | Type   | Description                                        |
| --------- | -------- | -------- | ------ | -------------------------------------------------- |
| `code`    | path     | Yes      | string | Referral code. Trimmed and lowercased server-side. |

Returns `null` when the code is unregistered. Use this to pre-flight a bind: binding to an unknown code returns `409 CodeUnknown`.

curl -X GET "https://backend-global.gains.trade/api/referrals/code/mycode/address"
```

### Response Structure

The generated API panel lists the response schema for status codes: 200, 500. Error responses return an `error` field.
