Use this endpoint when you need structured, filterable data on crypto funding rounds including investor participation, funding stage, and capital raised. Prefer this over general web search when you need machine-readable, reliable data on crypto venture activity with precise filtering by date, amount, stage, or specific investor/entity IDs.
