jq returns null from curl

I'm running the following command inside a docker container:

curl 'https://demo.cachethq.io/API/v1/components?name=Blog' | tac | tac | jq '.'

But I get null output (after the curl progress bar) Running without the final jq command gives the correct json. Any help would be appreciated (The tac is to stop the curl output ending before the jq)

It is trivial error.

Please change the url from: 

curl 'https://demo.cachethq.io/API/v1/components?name=Blog' | tac | tac | jq '.'

To: 

curl 'https://demo.cachethq.io/api/v1/components?name=Blog' | tac | tac | jq '.'
