A Simple BASH Script to Query to Cryptocurrency

Here is a quick BASH script that allows you to do something like this:

./ticker
e.g. ././ticker steem usd
./ticker steem usd
"1 steem = 0.21412699896499998 usd"
./ticker 2 steem gbp
"2 steem = 0.3794 gbp"
./ticker eth 2 btc
"26.331085755738364 eth = 2 btc"

#!/bin/bash

check_json=$(echo "{ }" | jq)
if [ "$check_json" != "{}" ]; then
        echo "jq not installed"
        exit 1
fi

if [ "$1" == "" ]; then
        echo "e.g. ./$0 steem usd"
fi

API="https://price.justyy.workers.dev/query/"

curl -s -X POST -d "$*" $API | jq .result[0]

This requires the jq to parse the JSON output from the Crypto API made by @justyy (myself) on cloudflare workers serverless technology.
