CB Insights API v1

name: CB Insights API v1
description: The original CB Insights REST API — 11 documented GET operations over organizations, deals
  (fundings, investments, portfolio exits), people, business relationships, expert collections and the
  credit ledger, authenticated with a 24-hour JWT from /v1/authorize. Fully documented in a static Hugo
  reference site with a dated change log through v1.9.0 (2024-07-26), but CB Insights publishes no OpenAPI
  for it and directs new integrations to v2.

x-spec-note: No machine-readable contract exists for v1. The reference is fully public and richly documented
  at api-docs.cbinsights.com, but CB Insights ships only Hugo-rendered HTML endpoint pages — probes of
  /openapi.json, /openapi.yaml and /swagger.json on that host all returned 404 on 2026-08-09. The v2 contract
  in openapi/ does not cover these operations.
