## Actions

### Get swap quote

Find out what a swap of a given size would cost right now: how much you would send and receive, at what price, and the limits on the swap. Give the amount you send or the amount you want to receive. Nothing is ordered. No API key required.

**Inputs**

- Pair (`pair`, text, required): The currency you receive followed by the currency you send, e.g. ETHBTC to receive ether for bitcoin. 'ETH/BTC' works too.
- Amount (`amount`, number, required): The amount to quote for, e.g. 0.01.
- Amount is (`amount_is`, text): Whether the amount is what you send or what you want to receive. Defaults to what you send. One of: `send` (What I send), `receive` (What I receive). Default: `send`.

**Outputs**

- `max_receive_amount` (number): The largest amount you can receive.
- `max_send_amount` (number): The largest amount you can send.
- `min_receive_amount` (number): The smallest amount you can receive.
- `min_send_amount` (number): The smallest amount you can send.
- `pair` (text): The pair, e.g. 'ETHBTC'.
- `price` (number): How much of the sent currency one unit of the received one costs.
- `quoted_at` (text): When n.exchange made the quote (ISO 8601, UTC).
- `receive_amount` (number): How much you would receive.
- `receive_currency` (text): The currency you receive, e.g. 'ETH'.
- `send_amount` (number): How much you would send.
- `send_currency` (text): The currency you send, e.g. 'BTC'.
- `summary` (text): One line, e.g. 'Send 0.01 BTC to receive 0.33674652 ETH on n.exchange'.

**Example output**

```json
{
  "max_receive_amount": 416.3854441243718,
