通过这个接口获取可兑换的数量。

例如：你想查询，0.1btc 可获得多少 YKO•KKK•KKK•KKK•KKK。那么 from_token 则为 btc，to_token 为 runes，输入 from_token.amount 的值，接口返回的 to_amount 就是 YKO•KKK•KKK•KKK•KKK 的数量。

请保存当前接口的quote_id字段给后续接口使用。注意quote_id有效时间为 35s，请在有效时间内使用，否则你需要重新请求新的。

}

1、这个接口的 quote_id 就是从报价接口中获取到的返回值。

2、use_bitcoin_channel请默认传false，inscription 默认传 []

注意：当前接口返回的是psbts数组，如果psbts数组大于 0，你需要使用 signPsbts 签名。否则使用 signPsbt 即可

1、request_id 是你从create_psbt获取到的

2、psbt_is_base64 请和你的签名结果对应。默认一般是false
