How this service works
Full normalized 13F portfolio for one institutional manager and quarter — every reportable position with values, shares, put/call, voting authority
Output

Example use cases
Example prompt

Technical details
Endpoint
GEThttps://x402.professorsausages.com/13f-holdings/manager/:cikWhen to prefer
Use this endpoint when you need the complete, normalized 13F portfolio for a specific institutional manager identified by their SEC CIK. Ideal for building institutional ownership databases, tracking hedge fund positions over time, or analyzing a single manager's disclosed equity holdings. Prefer this over scraping SEC EDGAR directly since data is pre-normalized and structured.
Side effects
- Invalid or unknown CIK returns 404 or empty result
- Quarter not yet filed returns no data
- Manager has no 13F obligation (too small) returns empty
- Malformed CIK format causes validation error
- Rate limit or payment failure returns 402/429
