Reddit Subreddit Search API. Subreddits matching your search.
Subreddits by keyword, with weekly visitors. We handle the proxies, blocks and platform changes.
Reddit Subreddit Search API at a glance
Searches public subreddits by keyword and returns them a page at a time, in Reddit's relevance order. Each has its name, ID, link, description and icon, whether it is marked NSFW or quarantined, and the exact weekly visitors and contributions Reddit shows beside it. Queries in any language work.
GET /v1/reddit/search_subreddits
- 1 credit per page, $0.75–$1.97 per 1,000 pages
- 17 typed fields null when unknown
- 10 subreddits per page, Reddit's relevance order

The response reference lists every field, its type and when it is null. See the full schema.
Null means unknown
A field Reddit doesn't show is null, never zero or an empty string, so a real zero always means zero.
What it accepts
Words to find subreddits by, matched by Reddit's community search against their names and descriptions (golang, home brewing, fußball).
Write one parser
Reddit, Facebook and X answer in these fields, so the code that reads one reads them all.
platformstring- Platform ID (reddit, facebook, …).
idstring- Platform-native community ID (string): Reddit's subreddit ID with its t5_ prefix, Facebook's numeric group ID.
namestring- The name its links use, without a prefix (golang for r/golang; a Facebook group's vanity name); null when it has none (a Facebook group known only by its number).
titlestring- The community's title as its page shows it ("The Go Programming Language"; what Facebook calls a group's name); null when it has none.
descriptionstring- Its short description as plain text; null when it has none.
urlstring- Canonical community URL (https://www.reddit.com/r/golang/, https://www.facebook.com/groups/<id>/).
avatar_urlstring- The community's icon or picture; null when it has none. Platform CDN URLs can expire.
banner_urlstring- Header or cover image URL; null when it has none.

Good to know before you build.
- Reddit ranks relevance per visitor. A walk keeps one logged-out session, so its pages follow one ranking, but two walks of the same query can differ.
- Reddit's search leaves NSFW and quarantined subreddits out logged out, so they aren't found here. The Reddit Subreddit API reads one by name.
- Results show only what Reddit's search shows: title, creation date, privacy, banner, member nickname and rules are null (rules listed in unknown_fields). The Reddit Subreddit API returns them.
- Reddit shows no subscriber count logged out, so metrics.member_count is null. platform_specific.reddit.weekly_visitor_count and weekly_contribution_count are the activity Reddit shows instead.
- Reddit's community search matches loosely: a query no subreddit name or description contains still returns Reddit's nearest matches.
- Reddit serves a limited number of result pages per search. A walk that reaches the last one ends with end_reason platform_limit.
