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. Part of the **telemetry-radar** layer, a newer set of endpoints built on the daily basket signal log. It is separate from the baskets under [Telemetry](https://docs.chicago.global/api-reference/telemetry/summary.md), which read the daily telemetry row directly. What changed in the telemetry baskets over a lookback window: quadrant changes, new divergences (fatigue or rebound), themes confirmed in more markets, and moves of 3 or more standard deviations. Each event carries the basket's current quadrant and momentum for context. > [!NOTE] > > Built from the daily signal log. From 2026-09-25 each day's signals are > recorded as seen that day, with no hindsight. Earlier dates come from a later > backfill run. Only active baskets are reported. ## 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. | An unknown value in `types` returns `400`. ## Response The window, counts per event type, and the events themselves (newest first, capped at `limit`). A `note` field appears only when more events matched than `limit` allows. `legend` explains each event type and is static. ```json theme={null} { "window": { "from": "2026-10-28", "to": "2026-11-04", "days": 7 }, "counts": { "quadrant_change": 2, "divergence": 1, "theme_spreading": 1, "big_move": 3 }, "total_events": 7, "events": [ { "basket_id": "jp-semiconductors-01", "basket_name": "Japan Semiconductors", "theme_id": "semiconductors", "market": "JP", "country": "Japan", "now": { "quadrant": "Leaders", "momentum_1m_pct": 4.21, "momentum_6m_pct": 11.03 }, "date": "2026-11-03", "type": "quadrant_change", "from": "Recovering", "to": "Leaders", "flips": 1, "momentum_1m_pct": 4.21, "momentum_6m_pct": 11.03 }, { "basket_id": "us-ai-infra-02", "basket_name": "US AI Infrastructure", "theme_id": "ai-infra", "market": "US", "country": "United States", "now": { "quadrant": "Fading", "momentum_1m_pct": -1.8, "momentum_6m_pct": 6.4 }, "date": "2026-11-02", "type": "big_move", "daily_zscore": -3.4 } ], "legend": { "quadrant_change": "The basket ended the window in a different quadrant than it started.", "divergence": "A divergence started: fatigue = down on the day while up month-to-date; rebound = up on the day while down month-to-date.", "theme_spreading": "The basket's theme is confirmed in more other markets than at the start of the window.", "big_move": "The day's move was at least 3 standard deviations from the basket's own history.", "now": "The basket's latest state, for context: quadrant and momentum (percent)." } } ``` ## OpenAPI ````yaml GET /v1/telemetry/changes openapi: 3.1.0 info: title: Parallax API description: >- Parallax by Chicago Global — AI-powered investment research and portfolio analytics.
