What is the Crunchbase API? And how to access it

Read on zapier.com

Summary

The Crunchbase API lets you query company, funding, and investor data via search, entity lookup, and autocomplete endpoints, and now adds AI‑powered predictions with probability scores. Access requires a paid Custom Data Access Plan (no free tier) and can be integrated directly, via Zapier, or through the MCP server.

  • Three lookup methods—search, entity lookup, autocomplete—cover both exact and fuzzy company queries.
  • AI predictions return probability scores for funding, acquisition, IPO, layoffs, etc., with back‑tested accuracy up to 95%.
  • The API is rate‑limited to 200 calls per minute and lacks native webhooks, so polling is needed for alerts.
  • Access is only via a negotiated Custom Data Access Plan; pricing starts at $79/mo (Pro) or $199/mo (Business).

Engineers building deal‑sourcing, CRM enrichment, or market‑monitoring pipelines need to know the API's capabilities, limits, and cost to decide if Crunchbase fits their data strategy.
