# Get Master Fiat Wallet

> Retrieve the merchant's master fiat wallet, including live balance and virtual account details

The master fiat wallet is the merchant-level settlement wallet (as opposed to a customer's individual fiat wallet). It is resolved from the authenticated API key, so no wallet ID is required.

## Request

<ParamField header="x-api-key" type="string" required>
  API Key for authentication
</ParamField>

## Request Example

```bash theme={null}
curl https://api-production.fossapay.com/api/v1/wallets/fiat/master \
  -H "x-api-key: fp_live_sk_xxxxxxxx"
```

```javascript theme={null}
const response = await fetch('https://api-production.fossapay.com/api/v1/wallets/fiat/master', {
  headers: {
    'x-api-key': 'fp_live_sk_xxxxxxxx'
  }
});

const data = await response.json();
const masterWallet = data.data;
```

```python theme={null}
import requests

url = "https://api-production.fossapay.com/api/v1/wallets/fiat/master"
headers = {"x-api-key": "fp_live_sk_xxxxxxxx"}

response = requests.get(url, headers=headers)
data = response.json()
master_wallet = data["data"]
```
