What it does

Lemmy is a federated link aggregator and forum, similar to Reddit, and every Lemmy server offers the same API. Read communities, posts and comments, for example /api/v3/post/list on lemmy.world, or vote, comment and post with a login token. Requests and answers are JSON, and RSS feeds exist for communities and users. Each server sets its own rate limits per IP address. Free, no key needed for reading.
