Get Trending Reddit Posts API

Fetch trending, hot, rising, top, or new posts from any subreddit with pagination and time filtering. Requires a Reddit session cookie in sessionCookies (obtain it from reddit-login.post, or copy reddit_session out of a signed-in browser) — Reddit has blocked every anonymous read surface since 2026-07-30.

How to call it

Send one POST to api.upapi.io/reddit-get-trending.get with your key in the X-Api-Key header and the parameters below as a JSON body. Each call spends 4 weighted units of your monthly quota. The operation times out after 60 seconds. Identical requests are served from cache for 300 seconds, unbilled.

Get Trending Reddit Posts API reference

Request parameters

time: string — Time filter for 'top' listing: hour, day, week, month, year, all
after: string — Pagination cursor
limit: integer — Max posts to return
listing: string — Listing type: hot, new, rising, top, controversial
proxyUrl: string — User-provided proxy URL
subreddit: stringrequired — Subreddit name (without r/)
sessionCookies: string — REQUIRED IN PRACTICE. Reddit account session cookies, as a JSON object or a '; '-delimited cookie header; the blob must contain reddit_session. Since 2026-07-30 Reddit blocks EVERY anonymous read surface, so a call without cookies returns a classified UPSTREAM_BLOCKED rather than data. Obtain the blob from reddit-login.post, or copy the reddit_session cookie out of a signed-in browser. A lead-gen account-pool row stores it nested at cookies->>'sessionCookies', not at the row's top level.
