Reddit Subreddits Search API

API 한 번의 호출로 Reddit Subreddits Search 데이터를 받아 가세요. Finds communities by topic. Every other Reddit endpoint on this API needs you to already know the subreddit you want; this is the one that answers which communities discuss a subject. Returns up to 25 communities with the name, the subscriber count, the description, the icon, the NSFW flag and the community URL. `author.id` is the bare community name in Reddit's own casing, which is exactly what `/v1/reddit/subreddit`, `/v1/reddit/subreddit/details` and `/v1/reddit/subreddit/search` take as their `subreddit` parameter, so a discovery call feeds a listing call with no re-mapping in between. The row is the same Author shape `/v1/reddit/subreddit/details` returns. The search surface publishes nothing else, so on a plain call `author.joined_at`, `author.ext.weekly_active_users`, `author.ext.weekly_contributions`, `author.ext.rules_text` and `author.ext.language` are null on every row. Send `include=details` and every row is joined, in the same call, to the details lookup that carries them: the community's creation date, weekly active users, weekly contributions and rules land on each row (rules stay null for a community that publishes none), and the language on most rows (it comes from a second source that can miss a row on a busy page, so treat it as usually present). When the details lookup's main source cannot answer a row, its second source still fills the creation date and the language and that row is billed as filled, but the weekly numbers and the rules stay null on it; `data.hydration` counts it among the filled rows. Cost: 1 credit for the page plus 1 credit per row filled from a fresh lookup (25 rows, so 26 at most); rows already in cache are filled for free, rows that could not be filled are refunded, and a repeat of the same call within the cache window is 0. Time: a plain call is about 1 second; `include=details` adds 3 to 9 seconds on a fresh page (the lookups run in parallel and the call waits for the slowest, never more than 12 seconds) and nothing when the rows are already cached. `limit=N` (1 to 25) takes the top N communities of the page and, with `include`, caps the extra credits at N. The response carries a `hydration` block itemising rows, lookups, cache hits, credits and milliseconds. The subscriber count on a search row is the search index's own figure; the join never overwrites a value the row already carries. Note the name: this is `subreddits/search` and it finds COMMUNITIES, where the singular `subreddit/search` searches posts INSIDE one community. Paginate with `cursor`. A query that matches nothing still returns communities rather than an empty list, which is Reddit's own search behaviour, so judge relevance on the rows.
