The 20 biggest score gainers and 20 biggest decliners over the last 7, 30, or 90 days.

Parameters

QueryRequiredValues
windowyes7d, 30d, 90d
A request with no window or an invalid value returns 400 { error: "window must be one of [...] " }.

When to use it

  • Daily / weekly “what’s moving” digest.
  • Spotting accelerating or distressed companies you don’t already track.
  • Validating that a thesis (e.g. “fintech is heating up”) is showing in the data.

Response

  "window_start": "2026-04-12T18:30:00Z",
  "window_end":   "2026-05-12T18:30:00Z",
  "gainers": [
    {
      "domain": "anthropic.com",
      "company_name": "Anthropic",
      "composite_now": 72.4,
      "composite_then": 64.1,
      "delta": 8.3,
      "ki_rating_now": "KI-1",
      "ki_rating_then": "KI-2+"
    },

  "decliners": [
    {
      "domain": "examplecorp.com",
      "company_name": "Example Corp",
      "composite_now": 41.0,
      "composite_then": 53.6,
      "delta": -12.6,
      "ki_rating_now": "KI-3",
      "ki_rating_then": "KI-2"
    },
    ...
  ]
}
delta = composite_now − composite_then. Both lists are sorted by |delta| DESC.

Eligibility for movers

A domain is eligible if it has at least two scoring runs: one inside the window and one before it. Newly-scored domains with no prior history are excluded — they have nothing to move against.

Caching

The full response is cached server-side for 5 minutes per (pipeline_version, window) pair. Two callers requesting ?window=30d 30 seconds apart get bit-identical responses.

No pagination

There’s no limit or cursor. Movers always returns 20 + 20. If you want a deeper view, compose /v1/distribution + per-domain /v1/score/{domain}/history.
