How can I add "current streak" of contributions from github to my blog?

Considering the GitHub API for Users doesn't yet expose that particular information (number of days for current stream of contributions), you might have to:

• scrape it (extract it by reading the user's GitHub page)
  As klamping mentions in his answer (upvoted), the url to scrap would be:
  https://github.com/users/<username>/contributions_calendar_data
https://github.com/users/<username>/contributions
  (for public repos only, though)

  SherlockStd has an updated (May 2017) parsing code below:

  https://github-stats.com/api/user/streak/current/:username

• try projects which are using https://github.com/users/<username>/contributions_calendar_data (as listed in Marques Johansson's answer, upvoted)

  • IonicaBizau/git-stats:

• akerl/githubchart (Github contribution SVG generator)
• akerl/githubstats (Github contribution statistics)

• build that graph yourself: see the GitHub project git-cal

git-cal is a simple script to view commits calendar (similar to GitHub contributions calendar) on command line.
Each block in the graph corresponds to a day and is shaded with one of the 5 possible colors, each representing relative number of commits on that day.

• or establish a service that will report, each day, any new commit for that given day to a Google Calendar (using the Google Calendar API through a project like nf/streak).
  You can then read that information and report it in your blog.

You can find various example of scraping that information:

• github_team_calendar.py
• weekend-commits.js

As in:

$.getJSON('https://github.com/users/' + location.pathname.replace(/\//g, '') + '/contributions_calendar_data', weekendWork);

• leaderboard.rb:

Like:

leaderboard = members.map do |u|  user_stats = get("https://github.com/users/#{u}/contributions_calendar_data")  total = user_stats.map { |s| s[1] }.reduce(&:+)  [u, total]end

• ... (you get the idea)

The URL for the plain JSON data was:https://github.com/users/[username]/contributions_calendar_data[Edit: Looks like this URL no longer works)

There is a URL which generates the SVG, which other answers have indicated. That is here:https://github.com/users/[username]/contributions

Simply replace [username] with your github username in the URL and you should be able to see the chart. See other answers for more in-depth explanations

If you want something that matches the visual appearance of GitHub's chart, check out these projects which use https://github.com/users/<username>/contributions_calendar_data but also apply other factors based on Github's logic.
