### Authenticate to API endpoints

To call the HTTP API endpoints on this page using `curl`:

For an insecure or local testing cluster, use HTTP:

{% include_cached copy-clipboard.html %}
~~~ shell
curl http://<host>:<http-port>/<endpoint>
~~~

For a secure cluster, authenticate to the HTTPS endpoint with [`cockroach auth-session login`]({% link {{ page.version.version }}/cockroach-auth-session.md %}#log-in-to-the-http-interface), then pass the authentication cookie to `curl`.

{% include_cached copy-clipboard.html %}
~~~ shell
cockroach auth-session login <user> --certs-dir=certs --only-cookie > $HOME/.cockroachdb_api_key
curl --cookie $HOME/.cockroachdb_api_key --cacert certs/ca.crt https://<host>:<http-port>/<endpoint>

Thanks for adding this! I wonder if this might be better more centralized somewhere since presumably these instructions work for all of the HTTP/HTTPS endpoints on this page?
