Is there any publicly accessible JSON data source to test with real world data?

Question

I'm working on a JavaScript dynamically loaded tree view user control. I'd like to test it with real world data.

Does anybody know any public service with an API that provides access to hierarchical data in JSON format?

Answer 1

Twitter has a public API which returns JSON, for example -

A GET request to:

https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=mralexgray&count=1,

EDIT: Removed due to twitter restricting their API with OAUTH requirements...

{"errors": [{"message": "The Twitter REST API v1 is no longer active. Please migrate to API v1.1. https://dev.twitter.com/docs/api/1.1/overview.", "code": 68}]}

Replacing it with a simple example of the Github API - that returns a tree, of in this case, my repositories...

https://api.github.com/users/mralexgray/repos

I won't include the output, as it's long.. (returns 30 repos at a time) ... But here is proof of it's tree-ed-ness.
