Git API for open source version

Question

Is there a git API/rest which I can use to determine open source version?
I mean I'll send the open source name and I'll get the current version of it.

Or better if possible :) Since we are using some open sources in our project I want to create some program/script which provide the open source names and version and find if there is new for minor or major update.

That is what VersionEye is doing.

And it has its own REST API

For example: https://www.versioneye.com/api/v2/products/c/git%2Fgit/versions?api_key=Log+in+to+get+your+own+api+token

Response Body:

{
  "name": "git",
  "language": "c",
  "prod_key": "git/git",
  "version": "2.6.4",
  "prod_type": "GitHub",
  "versions": [
    {
      "version": "2.3.0-rc2",
      "released_at": "2015-01-27T22:39:53.000+00:00",
      "released_string": "2015-01-27 22:39:53 UTC"
    },
    {
      "version": "2.3.0-rc1",
      "released_at": "2015-01-21T01:35:41.000+00:00",
      "released_string": "2015-01-21 01:35:41 UTC"
    },
    ...

It is actually free for opensource, and not free for private repos .

It is the only one I know which monitors all opensource.
You have other referentials usually dedicated to a language, like for instance godoc.org (for the golang opensource projects), with its own API , but limited to a language.
