# get13FHolders

**Identifier:** `sec_get13FHolders`

**Provider:** [SEC](https://kirha.com/providers/sec.md)

Find institutional managers whose 13F-HR reports a given security (by CUSIP) for a quarter, with each manager's shares and value. Uses EDGAR full-text search, so it returns a sample of holders (not ranked by position size) plus the approximate total number of filers; use get13FHoldings to check one specific manager. Get the CUSIP from get13FHoldings output or a ticker lookup tool.

## Run it with the CLI

```bash
kirha tools run sec_get13FHolders \
  --input '{
    "cusip": "037833100 for Apple"
  }'
```

`--input` takes a JSON object that matches the input schema. Pass `--input -` to read it from stdin.

## Call it over HTTP

```bash
curl https://api.kirha.com/tools/v1/execute \
  --request POST \
  --header 'Content-Type: application/json' \
  --header 'Authorization: **********' \
  --data '{
  "tool_name": "sec_get13FHolders",
  "input": {
    "cusip": "037833100 for Apple"
