I've looked at the githooks manpage but unless I'm missing something I don't see an option for local, post-push git hooks. I'd like to have one that updates the api docs on my web server (for which I already have a script) after I push the master branch to the GitHub repo. Of course I could just write my own script that combines the git push and the api docs run, but that feels somewhat inelegant.

From Git 1.8.2 there is a new hook invoked before the push operation: pre-push If the script returns other than 0 the push operation will be cancelled.
Mention in the release notes: https://github.com/git/git/blob/master/Documentation/RelNotes/1.8.2.txt#L167
Implementing a post-push hook is in fact possible by using the reference-transaction hook. After a push is done, git will locally update the remote tracking branch, triggering a reference transaction on refs/remotes/REMOTE/BRANCH.
Here's an example for a hook that uses this technique:
#!/bin/bash
set -eu
while read oldvalue newvalue refname
do
if [ $1 = committed -a $refname = refs/remotes/origin/main ]
then
exec .git/hooks/post-push
fi
done
This script must have the executable bit and be placed in .git/hooks/reference-transaction. The hook runs after pushing the main branch to origin. Put your actual hook script in .git/hooks/post-push.
Just create a pre-push hook with a sleep at the top. Ensure sleep is long enough for the commits to be uploaded to upstream server based on your network connection speed. Ideally add a & to run your script in the background:
(sleep 30 && .git/hooks/post-push) &
