Do you know about the --libcurl option? It can write your code for you.

--insecure is a bad idea, especially when you're sending credentials over the
wire. You should fix your certificate store so that it's not needed.

This is seldom needed because curl adds it on its own.

Date: on a request? I've never seen that before. Is that needed by AWS
signatures?

This one doesn't make much sense on a GET request, because there is no content
being sent. Did you really want Accept:?

curl versions since 7.75.0 have AWS signature calculation built-in, with the
--aws-sigv4 option.

This is a very simple request with one custom header, so simple.c will do fine
with the addition of CURLOPT_HTTPHEADER which you can see how to do in many
other examples. But look at the curl's built-in AWS support first.
