Unauthorized error for bitrise api

[chintan.pathak]

I received the below error whenever I execute any API:-
{
“message”: “Unauthorized”
}

Am I missing some authorization as I have personal token but i have no idea about how to pass that token in the API.
My main intention is to get the public url from the API:- /apps/{app-slug}/builds/{build-slug}/artifacts/{artifact-slug}
and I have set the version code and app title variable when we click on ‘eye symbol’ in the app dashboard, so is there any way to achieve this?

Thank you

You need to add token via header.
See how it is done using Authorize button on the same page you linked:
