Blobs are files in the Git repository.
If you haven't already, look at the information on getting started with these APIs.
Get a blob
When you get an blob, by default the response is a stream (application/octet-stream) that contains the contents of the file.
GET https://{instance}/DefaultCollection/{project}/_apis/repos/git/repositories/{repository}/blobs/{objectId}?api-version={version}[&download={bool}&fileName={string}]
| Parameter | Type | Default | Notes | 
|---|---|---|---|
| URL | |||
| instance | string | TFS server name ({server:port}). | |
| project | string | ID or name of the project. Optional if specifying an ID for repository. | |
| repository | string | ID of the repository. | |
| objectId | string | SHA1 hash of the file. You can get the objectId of a file by getting its metadata. | |
| Query | |||
| api-version | string | Version of the API to use. | |
| $format | enum | Accept header | Options: json,zip,text,octetstream. If not set, defaults to the MIME type set in the Accept header. | 
| download | bool | false | If true, prompt for a download rather than rendering in a browser. Note: this value defaults to true if $format is zip | 
| fileName | string | object ID | Provide a fileName to use for a download. | 
Note
Repositories have both a name and an identifier. Identifiers are globally unique, but several projects may contain a repository of the same name. You don't need to include the project if you specify a repository by ID. However, if you specify a repository by name, you must also specify the project (by name or ID).
