Reddit API: read the full moderator list of subreddits
TL;DR
About
Developers looking for a Reddit API to read the full moderator list of a subreddit usually find there is none they can use: Reddit's API needs a registered app and OAuth, and its mod-list endpoint is closed to logged-out callers. This script fills that gap. It works like an API endpoint — one call with typed arguments, a JSON response — but runs through a real browser, yours or a hosted one, so it needs no Reddit developer account, API key or app review.

}FAQ
Get Reddit thread
Fetch a full Reddit thread from its URL. Returns title, op_text, score, num_comments, and comments (author, body, score, nesting depth). Compare num_comments to total_comments to detect truncation; use all_comments to expand every "more replies" thread automatically.
Get subreddit threads
List a subreddit's threads by Reddit's native sort (best/hot/new/top/rising). "new" is chronological (filter with `since`); "top" takes a `time` window (hour…all); others paginate by `limit`. Returns url, title, author, score, num_comments, created, post_type, and body — the post's full text (never truncated; null for link/image posts). `limit` is a maximum, not a guarantee: fewer matching threads returns what exists.
Search Reddit
Search posts across all of Reddit (no subreddit restriction), with optional sort and time window. Returns count and threads (each with id, url, title, author, subreddit, score, num_comments, created, nsfw, preview_text). `limit` is a maximum: fewer matching posts than requested returns however many exist. Useful to discover which subreddits discuss a topic. The sort changes how relevant the results are: `top` orders Reddit's matches by score, and because Reddit matches loosely, a heavily upvoted post only tangentially related to the query can outrank the genuine matches. That is Reddit's own ranking, returned as-is. Use the default `relevance` sort when on-topic results matter, and treat a non-zero count under `top` as "Reddit returned something", not as proof the posts are about the topic. Reddit refuses connections from datacenter addresses, so this works as-is on your own browser; on a hosted cloud browser the session has to be given a country so it exits through a residential address, otherwise Reddit blocks it and the script says so.
