When to prefer

Use this endpoint when you need to identify which investors participated in specific crypto funding rounds, filter by funding stage, entity, amount range, or date window, and need structured investor-level participation data. Prefer this over the sibling funding rounds endpoint when the focus is on investor identity and participation patterns rather than round-level aggregates.
