BASH Script to Query and Monitor the Crypto Prices (Exchange Rate to Fiat)

BASH Script to Query and Monitor the Crypto Prices (Exchange Rate to Fiat) | ninjasquad

With the Crypto Price Lookup API and the JSON jq tool, we can make a simple bash script to query crypto prices such as bitcoins, TRON, steem:

#!/bin/bash
# filename: ticker
 
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]

#!/bin/bash
# filename: ticker

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]

Example usages:

$ ./ticker btc
"1 BTC = 15657.051999999998 USD"
$ ./ticker eth
"1 ETH = 1107.6736666666666 USD"
$ ./ticker btc gbp
"1 btc = 13765.275 gbp"
$ ./ticker 2 btc eur
"2 btc = 31593.86 eur"
$ ./ticker 2 btc eth
"2 btc = 28.362718608445565 eth"
$ ./ticker btc 2 eth
"0.141076979417348 btc = 2 eth"

$ ./ticker btc
"1 BTC = 15657.051999999998 USD"
$ ./ticker eth
"1 ETH = 1107.6736666666666 USD"
$ ./ticker btc gbp
"1 btc = 13765.275 gbp"
$ ./ticker 2 btc eur
"2 btc = 31593.86 eur"
$ ./ticker 2 btc eth
"2 btc = 28.362718608445565 eth"
$ ./ticker btc 2 eth
"0.141076979417348 btc = 2 eth"

Simple BASH Script to Query the Crypto Prices

The BASH sends a simple API request and parse the JSON response via the jq which will need to be installed via apt install jq.

We can monitor a command by using the watch command (parameter -n gives the interval to run the command), and we have the following tailored script so that we can query multiple coins re multiple fiat currencies at the same time:

#!/bin/bash
# filename: coin
 
check_json=$(echo "{ }" | jq)
if [ "$check_json" != "{}" ]; then
        echo "jq not installed"
        exit 1
fi
 
if [ "$1" == "" ]; then
        echo "e.g $0 btc"
        exit 2
fi
 
API="https://price.justyy.workers.dev/query/"
for i in $*; do
        for j in USD GBP EUR CNY; do
                ticker=$(curl -s -X POST -d "$i $j" $API | jq .result[0] | awk '{printf "%.3f", $4;}')
                echo "1 $i = $ticker $j"
        done
        echo -------------------------
done

#!/bin/bash
# filename: coin

check_json=$(echo "{ }" | jq)
if [ "$check_json" != "{}" ]; then
        echo "jq not installed"
        exit 1
fi

if [ "$1" == "" ]; then
        echo "e.g $0 btc"
        exit 2
fi

API="https://price.justyy.workers.dev/query/"
for i in $*; do
        for j in USD GBP EUR CNY; do
                ticker=$(curl -s -X POST -d "$i $j" $API | jq .result[0] | awk '{printf "%.3f", $4;}')
                echo "1 $i = $ticker $j"
        done
        echo -------------------------
done

Example usage:

1 2	# every 60 seconds $ watch -n 60 ./coin BTC ETH STEEM TRX

# every 60 seconds
$ watch -n 60 ./coin BTC ETH STEEM TRX

Monitor the Crypto Prices in BASH (via monitor)

Note that the Cryptos are volatile and do know how to manage your risks!
