# API v1 currencies

> Understand money and currency fields in API v1.

API v1 price fields include a currency code.

Supported currencies:

| Code  | Currency     |
| ----- | ------------ |
| `CZK` | Czech koruna |
| `EUR` | Euro         |

## Money fields

API v1 returns decimal price amounts.

```json theme={null}
{
  "amount": 18924,
  "currency": "CZK"
}
```

Lowest-price fields use `amount_per_night`:

```json theme={null}
{
  "amount_per_night": 1024.5,
  "currency": "CZK"
}
```

Some price responses are keyed by language because the returned currency follows
the localized booking context.

`POST /booking` accepts a `currency` value. If you omit it, API v1 defaults to
`CZK`.
