Pass sort rank_change and a window on get_top_trends to list Reddit World News climbers versus a prior snapshot. This stamp returned count 0 on 1d, 3d, 7d, 14d, and 30d.
Live data as of 2026-08-29
Reddit World News rank_change on Trends MCP is get_top_trends with type Reddit World News, sort rank_change, and a window such as 1d. From the August 29, 2026 pull, the board stamped 2026-08-29T00:01:41 UTC. Windows 1d, 3d, 7d, 14d, and 30d each returned count 0. The 1d, 3d, and 30d calls used a held-or-fell note. The 7d and 14d calls used a complete-turnover note. Default sort rank filled 25 headlines at limit 50, then count 0 at offset 25. Rank 1 was the r/WorldNews live thread for Russian Invasion of Ukraine Day 1647. Rank 2 was the United States and Israel launch attack on Iran discussion thread. Free tier access is 100 requests per month.
From the Trends MCP scan of August 29, 2026, Reddit World News sort rank_change stamped 2026-08-29T00:01:41 UTC and filled zero climber rows on every requested window. Window 1d used baseline 2026-08-28T00:01:38 UTC. Window 3d used baseline 2026-08-26T00:01:34 UTC. Window 7d used baseline 2026-08-22T00:01:36 UTC. Window 14d used baseline 2026-08-14T20:01:41 UTC, a 20:01 clock rather than the 00:01 World News cadence on 1d. Window 30d used baseline 2026-07-29T22:01:40 UTC, a 22:01 clock. Count stayed 0. Data stayed an empty array.
Default sort rank on that stamp returned 25 headlines at limit 50, then count 0 at offset 25. Rank 1 was /r/WorldNews Live Thread: Russian Invasion of Ukraine Day 1647, Part 1 (Thread #1794). Rank 2 was the Iran discussion thread numbered 21. Rank 3 was Canadian city considers renaming Trump Avenue to "Taco Avenue". Rank 6 was Iran's navy says it has full control over Strait of Hormuz. Rank 7 was King Harald V of Norway has died at age 89. Rank 22 was the Lake Ontario rename headline. None of those titles appeared as climbers because no climber list was returned.
Offset 25 on the 1d climber call then returned count 0 with the same held-or-fell note. That note is the empty-page message after a 0-row set, not a second page of movers. The Reddit World News API hub covers the current-rank board. This page covers the empty climber object that board produced on this stamp.
On this stamp a longer lookback did not add movers. It changed the empty-list note. Windows 1d and 3d printed: no items on the current board climbed versus the baseline; everything held or fell. Window 7d printed: the board turned over completely versus the baseline; no item appears in both snapshots, so no rank change can be computed. Window 14d used that complete-turnover note too. Window 30d switched back to held-or-fell.
Held-or-fell is overlap without a climb. Complete turnover is no overlap at all. A 30d held-or-fell note means at least one title from 2026-07-29T22:01:40 UTC still sat on the August 29 board, and that title did not gain rank. Persistent live threads are the obvious candidates. Rank 1 still named Day 1647 and Thread #1794. Rank 2 still named Thread #21. Those strings can survive a month of unique headlines rotating underneath them.
| Window | Baseline stamp (UTC) | Count | Note |
|---|---|---|---|
| 1d | 2026-08-28T00:01:38 | 0 | held or fell |
| 3d | 2026-08-26T00:01:34 | 0 | held or fell |
| 7d | 2026-08-22T00:01:36 | 0 | complete turnover |
| 14d | 2026-08-14T20:01:41 | 0 | complete turnover |
| 30d | 2026-07-29T22:01:40 | 0 | held or fell |
Read the note field. A 7d call can be empty because every headline is new. A 1d call can be empty because overlapping headlines held or fell. The window label does not pick the story. The get_top_trends pagination page already recorded that this family of Reddit boards stops at 25 on current rank. rank_change on that 25-row board can stop at 0.
Reddit Hot Posts used the same as_of 2026-08-29T00:01:41 UTC and the same 1d baseline 2026-08-28T00:01:38 UTC, then returned count 2. Both rows were the title meirl: rank 8, prev_rank 22, rank_change 14, then rank 12, prev_rank 22, rank_change 10. World News 1d on that stamp returned held-or-fell. Two Reddit types, one timestamp, two results.
Google News Top News 1d on a later stamp, 2026-08-29T12:02:07 UTC versus baseline 2026-08-28T02:01:40 UTC, returned count 0 with a complete-turnover note. Wikipedia Trending 1d on that 12:02 stamp filled 25 climbers at offset 0. Rank 21 Grand Theft Auto VI listed prev_rank 157 and rank_change 136. Rank 25 Nepal listed prev_rank 66 and rank_change 41. Wikipedia paginated past 25 on earlier pulls. World News did not.
The Reddit Hot Posts rank_change API page recorded the meirl duplicate on this same 00:01 stamp. World News did not share that recycled generic title. Unique news headlines rotate off. Sticky live threads stay. The empty climber list is the product of that mix, not a missing snapshot. The Google News versus Reddit World News comparison stays useful when one feed prints complete turnover and the other prints held-or-fell.
MCP and REST both take type Reddit World News. REST wraps it in mode get_top_trends. Sort rank_change and a window are optional; omit them for the current board.
{
"mode": "get_top_trends",
"type": "Reddit World News",
"sort": "rank_change",
"window": "1d",
"limit": 50,
"offset": 0
}
Window accepts 1d, 3d, 7d, 14d, or 30d. Default window is 30d when sort is rank_change and window is omitted. On this stamp that default would have returned the 30d held-or-fell object, not a climber table. Ask for 1d when the question is yesterday. Read count before paging. Offset 25 after a 0-row 1d call repeated the held-or-fell note.
Current rank uses the same type string without sort:
{
"mode": "get_top_trends",
"type": "Reddit World News",
"limit": 50,
"offset": 0
}
On this pull the second call still returned count 25. Raising limit to 50 did not invent ranks 26 through 50. get_top_trends is billed per feed type and per page. One rank_change call is one request, separate from a default sort rank call. Free covers 100 requests per month. Starter is $19 for 1,000. Extra percent_growth windows inside one get_growth call still count as a single request.
MCP clients send the same type string Reddit World News. REST uses mode get_top_trends. The string is case-sensitive. Close labels such as Reddit WorldNews fail.
get_growth with source reddit and keyword worldnews is subreddit subscriber history, not a score for one headline. The series printed 26 daily points from 2026-08-01 through 2026-08-28. Preset 3M returned date_out_of_range with data_start 2026-08-01 and data_end 2026-08-28. Recent_date 2026-08-28 showed recent_value 7.1 and recent_volume 1,141. The 7D window compared 7.1 / 1,141 versus 24.4 / 1,483: index -70.9%, volume -23.06%. The 14D window compared 7.1 / 1,141 versus 9.5 / 1,188: index -25.26%, volume -3.96%. The 30D window compared 7.1 / 1,141 versus 21.7 / 1,430: index -67.28%, volume -20.21%. A full 25-row news board can sit next to a down week on the subreddit series.
google search for King Harald V used 260 weekly points with recent_date 2026-08-22. Recent_value was 1.0 versus 1.0 on 7D (flat), 1.0 on 14D (flat), 2.0 on 30D (-50.0%), and 2.0 on 3M (-50.0%). The death headline sat at live rank 7 on August 29. The search object was still a floor-1 weekly point dated a week earlier. wikipedia for King Harald V of Norway returned 404 no_data. Live rank is not a Wikipedia series.
google search for Strait of Hormuz used 260 weekly points, recent_date 2026-08-22, recent_value 14.0. The 7D window compared 14.0 versus 28.0 (-50.0%). The 14D window compared 14.0 versus 23.0 (-39.13%). The 30D window compared 14.0 versus 28.0 (-50.0%). The 3M window compared 14.0 versus 24.0 (-41.67%). Rank 6 on World News was a navy-control headline. Search heat on the strait name was already down from the prior week.
google search for Lake Ontario used 260 weekly points, recent_date 2026-08-22, recent_value 8.0 versus 9.0 on 7D (-11.11%), 8.0 on 14D (flat), 10.0 on 30D (-20.0%), and 9.0 on 3M (-11.11%). The rename headline sat at live rank 22. google search for South Korea conscription returned 404 data_unavailable. A rank 5 headline does not guarantee a search object.
Live World News rank is a title on a 25-row r/worldnews board. rank_change is overlap versus a named baseline, and on this stamp that overlap never produced a climb. get_growth with source reddit is a short daily subscriber series that can refuse 3M. google search is a weekly index that can sit at 1.0 under a death headline. Quote the note, the count, and the recent_date. Do not treat a World News rank as a search peak.
