REST and Workers bindings manage Artifacts repos and read history, commits, trees, blobs, or a file at a ref without cloning. Git provides clone, fetch, and push. The documented APIs expose no direct file-write or merge method; clients create commits and push them.

Three interfaces to the same repository

Interface	Useful operations
REST	Repository lifecycle, Git-token lifecycle, history and direct object/file reads
Workers binding	Similar operations from Worker code, including log, readCommit, readTree, readBlob, and readFile
Git over HTTPS	Clone, fetch, and push with a repository Git token

For a small inspection, read a file by path and branch/tag/commit through REST or the binding. For editing a workspace, use a Git client or library, create commits, and push. Diff and merge are client Git operations; the current REST/binding reference does not expose dedicated diff, merge, or file-write methods.

Git tokens authenticate Git routes, not management REST requests. See the earlier credential distinction.
