How this service works
All institutional holders of one security in a quarter, by ticker or CUSIP, with concentration and quarter-over-quarter institutional flow. This reverse index is deferred on this deployment and returns availability status; a manager's crypto ETF exposure is covered now by the holdings manager route.
Output
A list of all institutional holders for the specified security in the requested quarter, including each holder's name, position size, concentration percentage, and quarter-over-quarter flow direction and magnitude. If the reverse index is deferred on this deployment, the response returns an availability status message instead of full holder data.
Example use cases
Institutional ownership snapshot for ETF
“Who are all the institutional holders of IBIT as of the latest quarter, and how has their ownership concentration changed quarter-over-quarter?”
CUSIP-based holder lookup for analyst
“Get me every institutional holder for the security with CUSIP 46090E103 for Q3 2024, along with each holder's concentration and flow data.”
Tracking institutional flows into a stock
“Which institutions were buying or selling NVDA last quarter? Show me the full holder list with concentration and quarter-over-quarter flow changes.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/holdings/securityWhen to prefer
Use this endpoint when you need a comprehensive view of ALL institutional holders of a single security, including concentration and flow analytics, and you have a ticker or CUSIP. Prefer this over the holdings-manager route when your query is security-centric (reverse index) rather than manager-centric. Note that crypto ETF exposure via manager is currently available on the companion holdings-manager route; this endpoint may return a deferral status for non-crypto securities on this deployment.
Side effects
- Reverse index deferred: endpoint returns availability status rather than full holder data for non-crypto-ETF securities
- Missing required identifier: request without ticker or CUSIP returns an error
- Invalid CUSIP format: 9-character requirement not met returns validation error
- Invalid quarter date format: non-ISO YYYY-MM-DD date returns parse error
- Security not found: unknown ticker or CUSIP returns empty or not-found response
- Rate limit or payment failure: x402 payment not processed returns 402 status
