Getting Jenkins Build Results through HTTP Get request - jenkins

Question

I'm trying to get test results from a Jenkins job and was wondering if it was possible to get the json results by making a GET request (e.g. to a certain job: JENKINS_URL/job/JOB_NAME/build/api/json) while not logged into the Jenkins server.
I am having trouble understanding how you can send all the how do you pass the authentication information in the API call (e.g. API token / password, username).
I know the Jenkins CLI is an option, but I would prefer not to use it if possible.
To be clear, when logged in on my computer, calls to JENKINS_URL/job/JOB_NAME/build/api/json yield the build results, but when I log out, the link takes me to the log in page.

You have to configure your credentials and give read access for anonymous or pass your user/password in your request:
curl --user username:password jenkins_url/job/job_name/build_number/api/json
The same but using api_token:
curl --user username:api_token jenkins_url/job/job_name/build_number/api/json
If you pass also?pretty=true parameter, you should see something like this:
{
"actions" : [
{
"parameters" : [
...
}
],
...
"building" : false,
"description" : null,
"displayName" : "#36",
"duration" : 1936,
"estimatedDuration" : 2020,
"number" : 36,
"queueId" : 224,
}
