[SOLVED] How to chain curl such that the output of one become another's input?

Issue

Could someone tell me how to pass the output of one CURL GET to another CURL POST? I mean something like this:

curl --header "Content-Type: application/json" --request POST --data "{\"specification\": curl --header "Content-Type: application/json" --request GET "https://user:pass@anotherhost"}" "https://user:pass@localhost"

Solution

Use jq to craft JSON in the shell.

response="$(curl --header "Content-Type: application/json" --request GET "https://user:pass@anotherhost")"
data="$(jq "{specification: .}" <<< "$response")"
curl --header "Content-Type: application/json" --request POST --data "$data" "https://user:pass@localhost"

Keep in mind, that passwords in command line arguments are public to the host.
