Im trying to retrieve the current difficulty value via api and parse the value only using JQ. In this example it is etherchains api. Currently my output is

curl 'https://etherchain.org/api/difficulty' | jq '.data'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    52  100    52    0     0    129      0 --:--:-- --:--:-- --:--:--   129
    "difficulty": 666836759051894

and I would like it to be


When I look at the jq manual https://stedolan.github.io/jq/manual/#Basicfilters it shows

    jq '.foo'
Input   {"foo": 42, "bar": "less interesting data"}
Output  42

What am I doing wrong?


Putting curl into silent mode first...

$ curl -s 'https://etherchain.org/api/difficulty' | jq '.data[][]'
  • what are the square brackets at the end doing? – sealfab Jun 12 '17 at 23:55
