Getting content for each file in a directory in a github repo using api - github-api

Question

I was searching through the api docs. It appear the same api call is being used for getting details except content when a dir is provided and content when a single file is given.
https://docs.github.com/en/rest/reference/repos#get-repository-content--code-samples
In the case of Response if content is a file
"type": "file",
"encoding": "base64",
"size": 5362,
"name": "README.md",
"path": "README.md",
"content": "encoded content ...",
"sha": "3d21ec53a331a6f037a91c368710b99387d012c1",
"url": "https://api.github.com/repos/octokit/octokit.rb/contents/README.md",
"git_url": "https://api.github.com/repos/octokit/octokit.rb/git/blobs/3d21ec53a331a6f037a91c368710b99387d012c1",
"html_url": "https://github.com/octokit/octokit.rb/blob/master/README.md",
"download_url": "https://raw.githubusercontent.com/octokit/octokit.rb/master/README.md",
"_links": {

"self": "https://api.github.com/repos/octokit/octokit.rb/contents/README.md",
"html": "https://github.com/octokit/octokit.rb/blob/master/README.md"
}
}
In case of Response if content is a directory
{
"type": "file",
"size": 625,
"name": "octokit.rb",
"path": "lib/octokit.rb",
"sha": "fff6fe3a23bf1c8ea0692b4a883af99bee26fd3b",

"html_url": "https://github.com/octokit/octokit.rb/blob/master/lib/octokit.rb",

}
},
{
"type": "dir",
"size": 0,
"name": "octokit",
"path": "lib/octokit",
"sha": "a84d88e7554fc1fa21bcbc4efae3c782a70d2b9d",
"url": "https://api.github.com/repos/octokit/octokit.rb/contents/lib/octokit",
"git_url": "https://api.github.com/repos/octokit/octokit.rb/git/trees/a84d88e7554fc1fa21bcbc4efae3c782a70d2b9d",
"html_url": "https://github.com/octokit/octokit.rb/tree/master/lib/octokit",
"download_url": null,
"_links": {

"git": "https://api.github.com/repos/octokit/octokit.rb/git/trees/a84d88e7554fc1fa21bcbc4efae3c782a70d2b9d",
"html": "https://github.com/octokit/octokit.rb/tree/master/lib/octokit"
}
}
]
How can I get the content too as an output field for all the files in a directory through a single api call. Is there any way to do so?
