I guess there is some confusion here.
The announced link referenced in the issue has artifact metadata APIs which include following endpoints

• POST /orgs/{org}/artifacts/metadata/deployment-record
• POST /orgs/{org}/artifacts/metadata/deployment-record/cluster/{cluster}
• POST /orgs/{org}/artifacts/metadata/storage-record
• GET /orgs/{org}/artifacts/{subject_digest}/metadata/deployment-records
• GET /orgs/{org}/artifacts/{subject_digest}/metadata/storage-records

However, the endpoint added in this PR GET /repos/{owner}/{repo}/actions/artifacts/{artifact_id}/metadata is not documented in GitHub API docs

Sorry @Not-Dhananjay-Mishra Sir , in the issue section nothing was clear like this. Now i get a clear idea now and i will read the whole description from https://docs.github.com/rest/orgs/artifact-metadata and after i will Raise a PR to this branch only .
Thank you for you Guidance. can you please provide any other relevant documentation which need to refer before raising a PR. it will be really helpful for me.
