Multiple Currency Pairs returned in Single API Call

Question

Does anyone know where can I find an API that outputs an array of cryptocurrencies (BTC, ETH, LTC, etc.) converted to USD?

For Example:

www.somesite.com/api/rest/baseCurrency=USD

Returns:

{
    "Data": {
        "BTC": {
            "Id": "1231",
            "Name": "Bitcoin",
            "CurrentAsk": "4481.01"
        },
        "ETH": {
            "Id": "3242",
            "Name": "Etherium",
            "CurrentAsk": "322.09"
        },
        "LTC": {
            "Id": "4354",
            "Name": "Litecoin",
            "CurrentAsk": "73.57"
        }
    }
}

I'm aware that I can make multiple API calls to get this information, but would rather retrieve the information I'm looking for in a single call.

Thank you

Liqui has an excellent API for currency pairs, and most importantly multiple currency pairs. Documentation can be found here.

Here is an example call that will produce calls for the following currency pairs (using USDt):

• BTC -> USD
• ETH -> USD
• LTC -> USD

Sample output:

{
    "btc_usdt": {
        "high": 4600.0,
        "low": 3956.08280896,
        "avg": 4278.04140448,
        "vol": 712485.2240255205420855,
        "vol_cur": 168.99447489,
        "last": 4379.41785788,

        "sell": 4413.6739016,
        "updated": 1504647325
    },
    "eth_usdt": {
        "high": 340.05294292,
