Request, inspect and script HTTP in a terminal.

curl

See the response, not just the body

curl -sS -D - -o /dev/null https://example.com

Fail on HTTP errors

curl -sSf https://example.com/api

-f makes curl exit non-zero on 4xx and 5xx. Plain -s hides errors and exits 0, which breaks scripts quietly.

Follow redirects and keep the method

curl -sSL -X POST -d 'a=1' https://example.com/hook

Set a timeout so scripts do not hang

curl -sS --max-time 10 --connect-timeout 5 https://example.com
