## How to call it through Zero

```sh
zero fetch --capability 2s-io-insider-sentiment-f95fda3b
```

Example prompt: What's the insider sentiment for Tesla (TSLA) over the past year — are executives and directors net buyers or sellers, and what does the monthly MSPR look like?

## When to prefer this

Use this endpoint when you need a distilled, aggregated monthly insider sentiment signal for a US-listed stock rather than raw individual insider filing data. Prefer this over manually parsing SEC filings when you want a clean MSPR score and net holdings delta by month, especially for trend analysis or comparative screening across companies.

## Known failure modes

- Invalid or non-US ticker returns empty results or an error
- Date range too narrow may return zero records
- Missing required ticker parameter returns a 400 error
- Ticker for a delisted company may return no data
- Service unavailability returns a 5xx error

## How this service works

Aggregated insider sentiment for a US-listed company, by month. For each month returns the net change in insider share holdings and Finnhub's MSPR (Monthly Share Purchase Ratio, −100 to +100 — higher means more net insider buying). Pass ticker and optionally a from/to window (YYYY-MM-DD; defaults to ~1 year). A distilled signal layered on top of raw insider filings. Data by Finnhub.

## Output

An array of monthly records for the requested ticker, each containing the month, net change in insider share holdings, and Finnhub's MSPR (Monthly Share Purchase Ratio, ranging from -100 to +100, where higher values indicate more net insider buying).
