}Telemetry Changes
What changed in the telemetry baskets over the last days: quadrant changes, new divergences (fatigue / rebound), themes confirmed in more markets, and moves of 3+ standard deviations. Built from the daily signal log: from 2026-09-25 it holds each day’s signals as recorded that day (no hindsight); earlier dates come from a later backfill. Each event carries the basket’s current state for context.

}Query Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
days | integer | No | 7 | Look back this many calendar days from the latest report. Range 1–90. |
market | string | No | — | Market code or country name to narrow to, e.g. JP or Japan. |
types | array of string | No | All types | Event types to include. Repeat the parameter for several. Valid values: quadrant_change, divergence, theme_spreading, big_move. |
limit | integer | No | 50 | Maximum events returned, newest first. Range 1–500. |
types returns 400.
Response
The window, counts per event type, and the events themselves (newest first, capped atlimit). A note field appears only when more events matched than
limit allows. legend explains each event type and is static.
