domain, DESC by scored_at. Paginated.
When to use it
- Plot a score trajectory chart.
- Detect rating changes (
KI-2+→KI-1). - Inspect how a particular event (funding round, leadership change, press coverage) moved the buckets.
Pagination
Defaultlimit=100, max 500. Responses include next_cursor when more pages exist:
curl "https://api.keplerinsights.us/v1/score/stripe.com/history?limit=50" \
-H "X-API-Key: ki_live_..."
{
"domain": "stripe.com",
"records": [

{ "scored_at": "2026-05-11T18:30:00Z", "composite_score": 77.9, "ki_rating": "KI-1+", ... }
],

What’s in a record
Each entry is a curated subset of the internal score record — the time-series core only. Notably absent vs the portal:- ❌
top_signals(with guidance cards) - ❌
executive_summary - ❌

Volume note
A company scored daily for 12 months has ~365 records, each <1KB after curation. The full table for a single domain fits comfortably in one or two pages oflimit=500. Don’t worry about volume.
Stale → fresh promotion
If you want the current score, don’t paginate to the head of the list — callGET /v1/score/{domain} instead. It’s a single-shot lookup and counts against your cached quota the same way.Authorizations
Live keys are prefixed ki_live_, test keys ki_test_. Issue + revoke
keys at https://console.keplerinsights.us. Never embed a key in client-side
code — every endpoint is backend-to-API only.
Path Parameters
Bare hostname. Strips a leading www. and any URL scheme automatically.
Query Parameters
Required range:
1 <= x <= 500Opaque pagination cursor. Pass back next_cursor from the previous response.
