CB Insights
CB Insights (CB Information Services, Inc.) is a New York-based private-market intelligence platform covering 12M+ private and public company profiles, funding deals, cap tables, M&A and IPO exits, business relationships, management and board data, and proprietary predictive scores (Mosaic, Commercial Maturity, Exit Probability, Competitor Score). The company exposes that data programmatically through the CB Insights API v2 — a token-authenticated REST API at api.cbinsights.com documented with a published Swagger 2.0 contract of 28 operations across Firmographics, Financial Transactions, Business Relationships, Management & Board, Outlook, Revenue, Strategy Map, Scouting Reports and the ChatCBI research LLM — plus a maintenance-mode v1 REST API, a hosted OAuth-protected MCP server at mcp.cbinsights.com listed in Claude, ChatGPT, Perplexity and Microsoft Copilot connector directories, a Snowflake Marketplace data share with Semantic Views and a Cortex Knowledge Extension, and Salesforce and Microsoft 365 Copilot connectors. Access is credit-metered and credential-gated: clientId/clientSecret are issued by CB Insights, exchanged for a 24-hour bearer token, and every data call debits an account credit ledger.
CB Insights publishes 11 APIs on the APIs.io network, including Authorization API, Business Relationships API, Chat CBI API, and 8 more. Tagged areas include Company, market-intelligence, private-company-data, venture-capital, and funding-data.
CB Insights’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 29 more developer resources.

- 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.

the deprecated self-hosted cbi-mcp-server reference implementation. Protected by OAuth 2.1 with dynamic client registration,
PKCE (S256) and RFC 9728 protected-resource metadata; connected from Claude, ChatGPT, Perplexity, Microsoft Copilot (Chat,
Researcher and Excel) via each client's connector directory. Live tools/list is auth-gated.
