How to get data related to Winter Bash?

Question

I was thinking of creating a nice question on Programming Puzzles & Code Golf related to Winter Bash 2014, but I need some specific data for that question - The number of hats of each user.

Is there a way to query the number of hats owned by a user using the stack exchange API?

Answer 1

The unofficial Winterbash inbox API

If you have any user's account_id then the hats information is just one call away.

And the call is

http://winterbash2014.stackexchange.com/api/inbox?accountId=<account_id>

For example, hats information about me can be retrieved via

http://winterbash2014.stackexchange.com/api/inbox?accountId=4996787

But here are the caveats:

• This is most probably a temporary API, so no idea how long it will work, or if it will change in between.
• I have no idea whether it works with an API key or not, thus for now, it only works for yourself It works for everyone who is participating in the WinterBash.

To get any user's account_id, simply use the /users API.

For example, a sample API for PPCG with name search on peter is

http://api.stackexchange.com/2.2/users?order=desc&sort=reputation&inname=peter&site=codegolf&filter=!)RwcIFaJnzoLPrdy_GOamMlj

which gives the following output

      "user_id": 194,

Answer 2

http://winterbash2014.stackexchange.com/api/user-hats?userId=29538&host=stackapps.com

This returns an array of arrays. Each inner array contains three integers:

• The Id of the hat
• The number of times the user has earned this hat, all over the network
• 1 if the user has earned this hat on this particular site (Stack Apps, in this example); 0 otherwise.
