**APIs profiled:** 7

Crunchbase is a leading source of private and public company, funding, and investor data - firmographics, funding rounds, acquisitions, investors, people, events, and AI-generated predictions and insights across the global startup and business landscape. The Crunchbase Data API (REST v4, base https://api.crunchbase.com/v4/data) exposes this graph programmatically through Entity Lookup, Search, Autocomplete, and Deleted Entities across 43 entity collections, and is published as six package-scoped OpenAPI 3.0.1 documents - Firmographic, Core Financials, Advanced Financials, Insights, Predictions, and Predictions & Insights - discoverable through an RFC 9727 api-catalog at data.crunchbase.com. Crunchbase also ships a first-party remote MCP server at mcp.crunchbase.com over Streamable HTTP with fourteen documented tools, authenticated with OAuth 2.1 + PKCE and sold as per-user MCP seats. The REST API is read-only and authenticated with a single account-level API key (user_key query parameter or X-cb-user-key header); which of the six packages that key is provisioned against determines which operations it can call. Access is subscription-gated with no published pricing - the full API requires a Crunchbase Enterprise or Applications licence, with a reduced Basic API for Crunchbase Basic plan holders.
