Using CURL to list github repository tree (github API) - api

Question

Using the github API, you can get a repository tree using (example done with CURL):
curl -H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/{owner}/{repo}/git/trees/{tree_sha}
Assuming I have a repo called dev by owner NewCo, and I want to list the repo tree called XXXX, I would:
curl -H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/NewCo/dev/git/trees/{tree_sha}
How can I find out the {tree_sha} value for tree XXXX? Any idea where can I find out this value?

You can use a commit sha from the commits endpoint for that: /repos/{owner}/{repo}/commits. For example:
#!/usr/bin/env bash
set -e
owner=zacanger
repo=fetchyeah
sha=$(curl -s -H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/$owner/$repo/commits?per_page=1 \
| jq -r '.[0].sha')
curl -H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/$owner/$repo/git/trees/$sha
You could also use the pull requests API, or any other endpoint that returns commit info (meaning, most of them except for user and org APIs).
