When to prefer

Use this endpoint when you need to identify the human or organizational entities responsible for managing crypto investment funds — especially useful for due diligence, competitive research, or building fund-manager relationship graphs. Prefer this over the funds listing endpoint when the focus is on who manages funds rather than fund financials.

Side effects

Invalid managerId format returns empty or error response
announcedAfter/announcedBefore date strings in wrong format cause parsing errors
raisedAmountMin greater than raisedAmountMax returns empty result set
Exceeding page/limit bounds returns empty data array
Missing payment (402 Not Paid) if x402 payment header is absent or insufficient
Rate limiting if too many calls are made in quick succession
