### Response example:

```
{
  "fees": {
    "networkFee": "2.2605",
    "fixFee": 0
  },
  "sourceCurrency": "CHF",
  "destCurrency": "BTC",
  "sourceNetwork": "fiat",
  "destNetwork": "bitcoin_mainnet",
  "sourceAmount": 100,
  "destAmount": "0.00398660113390708486776"
}
```

"destAmount" is the **net final amount**, which includes all applicable fees.

{% hint style="info" %}
The endpoint returns an error in case of an off-ramp if the amount is inferior the minimum amount of CHF 50 (or equivalent in other fiat currencies).
{% endhint %}

To know via API the **minimum off-ramp amount**, you can use:

<https://api.mtpelerin.com/currency_rates/sellLimits/:currency> (GET)

Replace :currency by one of our supported currencies.

Example: <https://api.mtpelerin.com/currency_rates/sellLimits/USD>

### Response example:

```
{
  "destCurrency": "USD",
  "limit": "62.341265"
}
```
