How this service works
13F institutional holdings rollup: top-held names, filer roster, per-ticker holder counts (top 300)
Output
Returns a structured data object containing: a ranked list of top-held ticker names (up to top 300, optionally truncated by limit), a roster of institutional 13F filers, per-ticker institutional holder counts, and metadata fields including data age in seconds, generated_at timestamp, stale and sample flags, product name, and disclaimer text.
Example use cases
Screening most institutionally crowded stocks
“Which stocks are the most crowded among institutional investors right now? Pull the 13F holdings rollup and show me the top 25 tickers by number of institutional holders.”
Building a smart money watchlist
“I want to build a watchlist based on what the biggest institutional filers are holding. Get me the top 100 names from the 13F holdings rollup so I can see which tickers appear across the most funds.”
Validating institutional conviction in a stock
“Before I take a position in a stock, I want to know how many institutional filers are holding it. Fetch the 13F rollup data and find where my ticker shows up in the holder count rankings.”
Technical details
Endpoint
GEThttps://insider-radar-agent.insider-radar-agent.workers.dev/v1/smart_holdingsWhen to prefer
Use this endpoint when you need a pre-aggregated, ranked rollup of institutional 13F holdings rather than per-filing or per-fund detail. Ideal for quickly identifying the most institutionally popular tickers, scanning the full filer roster, or checking holder counts across the top 300 names without parsing raw SEC EDGAR data yourself. Prefer this over direct SEC data sources when you need fast, structured, ready-to-use institutional sentiment signals.
Side effects
- Stale data flag set to true if underlying 13F data has not been refreshed recently
- Sample flag set to true if serving demo/partial data rather than full dataset
- Limit parameter exceeding 1000 returns validation error
- Network or upstream data provider unavailability may cause timeout or empty response
- Data may lag official SEC 13F filing deadlines by weeks given regulatory reporting cadence
