How this service works
Quarter-over-quarter 13F position changes for an institutional manager — Parses a fund's 13F-HR information tables and diffs the latest quarter against the prior one: new positions, exits, increases, decreases (with share deltas), and the change in top-10 concentration. CIKs may be zero-padded or not.
Output
A structured diff of the fund's 13F-HR filings between two consecutive quarters: lists of new positions (entered this quarter), exited positions, increased holdings with share deltas, decreased holdings with share deltas, and the change in top-10 position concentration.
Example use cases
Example prompt
“Pull the quarter-over-quarter 13F diff for Pershing Square Capital (CIK 0001336528) for Q3 2024 — I want to see new positions, exits, and any big changes in share counts.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/edgar/13f/:cik/diffWhen to prefer
Use this endpoint when you need a ready-made quarter-over-quarter diff of SEC 13F-HR filings for a specific institutional manager identified by CIK. It saves the work of parsing EDGAR XML, reconciling position tables across quarters, and computing share deltas yourself. Prefer this over raw EDGAR access when you want structured, normalized change data in a single call.
Side effects
- CIK not found or invalid — returns 404 or empty result
- Fund has not filed a 13F for the requested quarter — returns error or null diff
- Prior quarter filing missing — diff cannot be computed
- Malformed CIK (non-numeric or too long) — validation error
- SEC EDGAR temporarily unavailable — upstream timeout
