Lobste.rs JSON API

Computing-focused link aggregator stories as JSON, fully open

Lobste.rs, a tightly moderated tech link aggregator, exposes its front pages and individual stories as JSON simply by appending .json to a URL. No key, no auth, and effectively unlimited for reasonable use. Great for a curated, lower-noise alternative to Hacker News.
