REST API endpoints for Git blobs

About Git blobs

A Git blob (binary large object) is the object type used to store the contents of each file in a repository. The file's SHA-1 hash is computed and stored in the blob object. These endpoints allow you to read and write blob objects to your Git database on GitHub. Blobs leverage these custom media types. For more information about the use of media types in the API, see "Getting started with the REST API."
