How this service works
Quarter-over-quarter change of an institutional manager's Form 13F portfolio. Give a CIK or name and get every position bucketed as new, added, reduced, sold out or unchanged, with per-position share and dollar deltas and a net flow summary, from two consecutive 13F filings, cited to both.
Output
A structured report containing every position from two consecutive 13F filings, each labeled as new, added, reduced, sold out, or unchanged, with per-position share count delta and dollar value delta, plus a net flow summary and citations to both underlying 13F filings.
Example use cases
Hedge fund position tracker for analyst
“What did Citadel Advisors add, reduce, or sell out of in their most recent 13F filing? Give me the full position-level breakdown with share and dollar deltas.”
New position detection for activist investing
“Show me every new stock position that Elliott Management initiated in their latest quarterly 13F — I want to know what they've been buying fresh.”
Net flow summary for a specific quarter
“Can you get the quarter-over-quarter portfolio changes for CIK 0001336528 for the quarter ending 2023-09-30 and tell me the overall net flow direction?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/holdings/changesWhen to prefer
Choose this endpoint when you need position-level, quarter-over-quarter delta analysis from SEC Form 13F filings — specifically the bucketing of positions into new/added/reduced/sold-out/unchanged categories with precise share and dollar deltas. Prefer this over raw EDGAR scraping when you want pre-computed change attribution and a net flow summary without building your own comparison logic. Best suited for hedge fund monitoring, portfolio drift analysis, and institutional investor research workflows.
Side effects
- Manager name not resolved — CIK not found for provided name string; recommendation to supply CIK directly
- No 13F filing found for the specified CIK or quarter — fund may not be a 13F filer or filing is not yet available
- Only one filing available — cannot compute quarter-over-quarter change if a prior quarter filing doesn't exist
- Invalid quarter date format — must be ISO YYYY-MM-DD period-end date
- Rate limiting or payment failure via x402 protocol at $0.05 USDC per call
