How this service works
Institutional (13F) ownership & flow for a stock (?ticker=<stock ticker>)
Output
A JSON object containing: the stock ticker and company name, a flow signal (ACCUMULATION, NEUTRAL, or DISTRIBUTION), total institutional ownership percentage, insider ownership percentage, total institution count, a list of top holders each tagged with their action (added/trimmed/held/new), position value in USD billions, and percent held, plus a human-readable interpretation of the quarter's flow. Data is sourced from SEC 13F filings via yfinance and reflects the most recently filed quarter (lagged ~45 days after quarter-end).
Example use cases
Smart-money signal for trading decision
“Before I add to my Tesla position, can you check whether institutions have been accumulating or trimming TSLA last quarter, and what percentage of the float they own?”
Research report on institutional backing
“I'm writing a report on GameStop — pull the 13F institutional flow signal, total institutional ownership, and the top 10 holders with their quarter-over-quarter changes.”
Screening stocks for institutional conviction
“Check the institutional flow for AMD — I want to know if smart money is piling in or pulling out, how many institutions hold it, and which ones added the most last quarter.”
Technical details
Endpoint
GEThttps://funds.lonestaroracle.xyz/fundsWhen to prefer
Choose FundFlow when you need a structured, per-call read on institutional 13F positioning for a US-listed equity — specifically the flow direction (accumulation vs. distribution), top holder breakdown, and ownership percentages. Prefer this over manual SEC EDGAR lookups or premium data terminals when you want a lightweight, pay-per-call API ($0.05 USDC) that aggregates and interprets quarterly filings. Note the inherent quarterly lag and long-only scope (no shorts/derivatives reported).
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty result
- Very small-cap stocks with few 13F filers may return sparse holder data
- Data is lagged by ~45 days after quarter-end — real-time positioning is not available
- Non-US-listed equities are not covered by 13F filings and will not return results
- Payment failure or insufficient USDC balance blocks the call via x402 protocol
