Technical details
Endpoint
GEThttps://market.memoryapi.org/x402/market/holdingsWhen to prefer
Use this endpoint when you need to quickly look up the most recent 13F filing metadata (date and SEC link) for a specific institutional investor by name or CIK, without needing to parse full holdings data. Ideal for compliance checks, research workflows, or surfacing filing recency for any known institution.
Side effects
- Institution not found by name or CIK — returns empty or error response
- CIK does not correspond to a 13F filer — may return no filings
- Institution has never filed a 13F — no results returned
- Name search is ambiguous — may return wrong or multiple institutions
- Payment failure via x402 — 402 status returned before data is served
