AWK command print number only

Question

I am trying to print just the number with this code, although I get the "XXX,version". Any ideas how I could fix it?

wget -O - https://bch-chain.api.btc.com/v3/block/latest 2>/dev/null | awk -F ':' '{print $3}'

613777,"version"

Any help is greatly appreciated.

Answer 1

Like this, using a proper json parser: jq :

curl -s 'https://bch-chain.api.btc.com/v3/block/latest' | jq '.data.height'

 output

613777
