The Guardian’s Open Platform is open for business. The Guardian’s Content API is now out of beta. Of particular interest: you can access basic article metadata (headline, URL and tags) without using an API key at all, and the API supports JSONP—just request format=json and include a callback=foo argument.

jsondns. A JSONP API for making DNS queries, with a nice URL structure.

Djangopeople JSON parser. Awesome—Andy McKay has compensated for the lack of an official DjangoPeople API by creating a JSONP screen scraped API and hosting it on App Engine. As far as I’m concerned this is an officially supported feature—I’ll make sure future site changes don’t break it, and when I do add an API I’ll try to keep it compatible and help Andy set up redirects.

IMG-2-JSON (via) I’m not the only person deploying simple JSON-P APIs on App Engine: Adam Burmister’s tool extracts dimension, mimetype and EXIF metadata when provided the URL to an image file.

jsontime. Nat and I threw this together this morning—it runs on Google App Engine and exposes Python’s pytz timezone library over JSONP.

hasAccount. Stuart proposes a light-weight API for letting any site know if a user has an account (and is signed in) on another service. I wouldn’t want to deploy this without being confident that my CSRF protection was in order.

Freebase developer documentation. The JSON API and particularly the query language are fascinating.
