Git blobs

The Git blob API lets you create and get a Git blob (binary large object), the object type used to store the contents of each file in a repository.

About the Git blob API

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. You can read more about the use of media types in the API here.
