description: 'Fundz is an event-first business intelligence platform, founded 2015, tracking 200,000+
  companies and surfacing funding rounds, executive changes, M&A activity, SEC filings (8-K, 10-K, 10-Q,
  Form D) and website modifications in real time. Rather than storing millions of static records it focuses
  on companies showing active signals, and scores them against each user''s criteria. The API exposes
  company profiles, fundings, SEC filings and fund formations from api.fundz.net with an API key in the
  Authorization header. It sits in the same category as Harmonic and Crunchbase, and competes explicitly
  on access: an API key is free and issued instantly with no card and no sales call, and pricing is published
  rather than quoted. Fundz also ships an MCP server listed on the official Model Context Protocol registry,
  and publishes an llms.txt.'

    note: CLAIM NOT CONFIRMED. The founder states "we publish an OpenAPI spec"; none was discoverable.
      404 on /openapi.json, /openapi.yaml, /swagger.json, /api-docs, /docs, /redoc, /spec, /v1/openapi.json
      and /.well-known/openapi.json at api.fundz.net, on app.fundz.net, and in the fundzwatch-mcp repository.
      No spec was modelled on their behalf — the gap is recorded instead.
