Politics 1d returned two climbers at ranks 138 and 139

From the Trends MCP scan of August 29, 2026, Google Trends by Category sort rank_change stamped 2026-08-29T20:01:36 UTC and filled 2 climber rows on Politics window 1d, 0 rows on 10 other tested category names, and 0 rows on Politics windows 3d through 30d, so a default sort rank pull at limit 25 never lists these mover fields.

Shared as_of 2026-08-29T20:01:36 UTC, window 1d, baseline 2026-08-28T22:01:30 UTC (~22 hours earlier):

Politics 1d climbers (both of 2):

Politics default sort rank at offset 125 returned 14 rows and closed at rank 139. Those two climbers were the last two titles on the current Politics board. Rank 1 was lake ontario. Rank 4 was alvin hellerstein hush money decision. Rank 7 was save america. Default limit 25 stops at oklahoma election results and never prints ranks 138 or 139.

Games default sort rank filled 25 at offset 0, 25 at offset 25, 25 at offset 50, then 14 at offset 75, closing at rank 89. Rank 1 was gta 6 release date. Rank 2 was ps5. Rank 3 was ps5 pro, which also sat at rank 89. The current-rank board for a category is documented on the Google Trends by Category API.

How to call sort rank_change on a category board

get_top_trends with type Google Trends by Category, category Politics, sort rank_change, and window 1d returns climber objects, and REST mode get_top_trends bills that call as one request per page, so one Politics 1d probe plus 10 other 1d category probes plus three longer Politics windows is 14 requests before any get_growth follow-up.

7d, 14d, and 30d returned insufficient snapshot history

A longer rank_change window on Google Trends by Category can fail before it compares ranks, because 7d, 14d, and 30d on this stamp set baseline_ts to null and returned count 0 with an insufficient-history note, while 1d and 3d set a baseline and then reported complete turnover.

The 7d note is not the held-or-fell sentence used on some other feeds. It is "Insufficient snapshot history for this feed." Empty is a real JSON body. Raising limit does not invent a baseline. Offset 25 on Games 1d repeated the complete-turnover note rather than paging into hidden climbers.

Growth follow-ups used source google search (weekly points, recent_date 2026-08-22, 260 points). huffpost sat at 60.0, flat over 7 days from 60.0, down 18.92% over 14 days from 74.0, down 14.29% over 30 days from 70.0. The full Politics climber title new hampshire senate seat polling returned HTTP 404 data_unavailable. The shorter keyword new hampshire senate sat at 10.0, down 33.33% over 7 days from 15.0, up 42.86% over 30 days from 7.0. Quote the error for the board string. Do not substitute the shorter series silently.

Overall Google Trends 1d filled 52 climbers on a later baseline

sort rank_change with window 1d is valid on type Google Trends from the same account, and on this August 29, 2026 stamp that overall feed used baseline 2026-08-29T02:01:36 UTC (~18 hours earlier, four hours after the category 1d baseline) and filled 52 climbers after two pages.

Overall Google Trends 1d, same as_of 2026-08-29T20:01:36 UTC:

The largest overall 1d climb was minnesota state fair at rank 86 from prev_rank 171, rank_change 85. google search sat at 29.0 on 2026-08-22, up 45.0% over 7 days from 20.0, up 107.14% over 14 days from 14.0, up 141.67% over 30 days from 12.0. Offset 50 returned adam ghekiere at rank 171 from 172 (+1) and slate at rank 178 from 179 (+1).

Overall Google Trends 7d against baseline 2026-08-23T02:01:37 UTC returned count 12. The top climber was dolly parton at rank 1 from prev_rank 191, rank_change 190. google search sat at 1.0, flat over 7 days, 14 days, and 30 days from 1.0. Entertainment current-rank 1 on the category feed was also dolly parton. Entertainment rank_change 1d still returned complete turnover, so a query can lead a category board and still have no 1d category climber row. jake lang appeared twice on the overall 7d list, both at current rank 64, once with prev_rank 143 / rank_change 79 and once with prev_rank 108 / rank_change 44. Store both objects.

Wikipedia Trending 1d filled 25 rows at limit 25 against that 02:01 baseline, led by Rukidi IV of Tooro at rank 17 from 183, rank_change 166.

Mixed boards, duplicate ranks, and weekly index lag

Omitting category on type Google Trends by Category mixes official boards into one payload, and on this stamp a limit 50 call returned 50 rows that reused rank 1 and rank 2 across Science, Games, Politics, Entertainment, and the rest, so a unique-rank parser under-counts the mix.

Rank 1 in that mixed page included lunar eclipse august 2026 (Science), gta 6 release date (Games), lake ontario (Politics and Law and Government), dolly parton (Entertainment), target costume (Shopping), and nepal (Climate). Each still carries its category label. Pass the official name when the query is one board.

gta 6 release date sat at Games current rank 1. google search sat at 34.0, up 36.0% over 7 days from 25.0. youtube sat at 15.0, up 50.0% over 7 days from 10.0. ps5 sat at Games rank 2, with google search 60.0, down 1.64% over 7 days from 61.0. save america sat at Politics current rank 7 and was an overall 7d climber (rank 67 from 142, rank_change 75), with google search 24.0, up 14.29% over 7 days from 21.0, down 4.0% over 14 days from 25.0, down 52.94% over 30 days from 51.0. alvin hellerstein hush money decision sat at Politics rank 4 and overall 1d rank 33 from 72 (rank_change 39); google search sat at 0.0 versus 0.0 on 7D and 30D with data_quality low. Quote 0.0 versus 0.0, not a dummy percent. lake ontario sat at Politics rank 1, with google search 8.0, down 11.11% over 7 days from 9.0.
