Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability holdings-security-34766b45
```

Example prompt: Can you pull all the institutional holders of IBIT for the most recent quarter, including their concentration and how their positions changed from the prior quarter?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
