browse_subreddit
Fetch posts from a subreddit sorted by your choice (hot/new/top/rising/controversial). Returns a post list with content, metadata, and a data_source field. With Reddit credentials (data_source "api") posts include score, num_comments, and upvote_ratio; without credentials, results come from Reddit's public RSS feed (data_source "rss") and those fields plus nsfw are null — see the response note and do not infer popularity from them.
