description: 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.

  notes: 'Contract discovery win. The RFC 9727 api-catalog at https://data.crunchbase.com/.well-known/api-catalog indexes
    six first-party OpenAPI 3.0.1 documents (109 unique operations, every one with an operationId, summary, tags and 200/400/404/500
    responses); all six were fetched 200 and saved verbatim to openapi/. They replace the four hand-modelled 6-operation specs
    from the first round, which are archived under openapi/_superseded-modeled/. Also found: a first-party remote MCP server
    at https://mcp.crunchbase.com with 14 documented tools, a real llms.txt, an RFC 9116 security.txt with a Vulnerability
    Disclosure Program, and RFC 8414 + RFC 9728 OAuth metadata. Honest zeros recorded: no official SDK in any registry (all
    17 github.com/crunchbase repos are forks), no A2A agent card, no AsyncAPI or webhook surface, no status page, no trust
    center or named certifications, no sandbox, no CLI, no idempotency contract, and no published price for API or MCP access.
    The PostmanCollection and OpenCollection pointers from the previous round were dropped: those files were generated from
    the now-superseded modelled specs, and Crunchbase publishes no public Postman workspace.'
