## 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 otto-ai-form-144-filings-3bd95599
```

Example prompt: Pull the latest SEC Form 144 filings for NVDA — I want to see which insiders have filed proposed sale notices in the last 90 days, how many units they plan to sell, and whether any are tied to a 10b5-1 plan.

## When to prefer this

Choose this endpoint when you need the earliest available public signal of insider selling intent — before a Form 4 is filed confirming an executed trade. Ideal for pre-trade monitoring, 10b5-1 plan tracking, and alerting workflows. Use this over Form 4 lookups when you want to detect proposed (not yet completed) insider transactions. Covers the most recent 90-day window with up to 20 notices.

## Known failure modes

- Invalid or unrecognized ticker symbol — returns empty or error response
- Ticker has no Form 144 filings in the 90-day lookback — returns notices array empty with zeroed summary
- SEC EDGAR data temporarily unavailable — degraded flag set in meta
- Ticker resolves to a non-US-listed security with no EDGAR record

## How this service works

Form 144 filings by ticker — SEC notices of PROPOSED insider sales, filed BEFORE the Form 4 that reports the executed trade: who intends to sell, units, the filer's own market-value estimate, broker, approximate sale date and Rule 10b5-1 plan dates. The earliest public read on insider selling intent; a notice is not a completed trade and may never be executed. Latest 20 notices in a 90-day lookback. Public-domain SEC EDGAR. $0.005 per call.

## Output

Returns a JSON object with: a list of up to 20 Form 144 notices (filed within the past 90 days) including seller details, security class, units to be sold, filer's market-value estimate, broker, approximate sale date, and Rule 10b5-1 plan adoption date where applicable; a summary with total notice count, distinct sellers, total units, aggregate market value in USD, amendment count, and date range; coverage metadata (truncation flag, lookback days, candidates found); and a generatedAt timestamp with a methodology link.
