Code Snippet

Node JS

import axios from "axios";
import crypto from "crypto";

const apiKey = "your-api-key";
const apiSecret = "your-api-secret";

const data = {
    fromCurrencySymbol: "INR", // optional
    toCurrencySymbol: "USDT", // optional
};

/*
    If you pass both, it gives 10 most recent rates with fromCurrencySymbol and toCurrencySymbol
    If you pass one, it gives 10 most recent rates with that fromCurrencySymbol or toCurrencySymbol, whichever one is passed
    If you pass none, it gives 10 most recent rates irrespective of currencySymbol
    If you pass either the fromCurrencySymbol or the toCurrencySymbol, remember -
    
    fromCurrencySymbol can only be of currenctType 'fiat'
    toCurrencySymbol can only be of currenctType 'crypto'

    currencyType of a currency can be checked here - 
    https://docs.tylt.money/tylt-cpg-crypto-payment-gateway/api-reference/supporting-apis/supported-base-currency-list

    For your reference - 
    fromCurrencySymbol can be 'INR' and other fiat currencies
    toCurrencySymbol can be 'USDT' and other crypto currencies
