## 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 dopaminedesk-stock-research-brief-b25684f1
```

Example prompt: Give me a quick stock research brief on NVDA — current price, daily change, and how many recent SEC filings they have on record.

## When to prefer this

Use this endpoint when you need a fast, combined snapshot of both live price data and SEC filing activity for a US-listed public company in a single call, especially in due-diligence or investment-research workflows where you want recent regulatory filings alongside current market price — without needing to stitch together separate market-data and SEC data sources.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty snapshot
- Non-US or OTC tickers may not be supported
- SEC data may be delayed or unavailable if upstream source is down
- Limit parameter out of range (below 1 or above 10) may cause a validation error
- Payment failure via x402/USDC results in 402 response before data is returned

## How this service works

Combine a current market quote with official recent SEC filing and insider-ownership filing metadata in one sourced company brief.

## Output

Returns a JSON object with the ticker symbol, success flag, a snapshot object containing current price, previous close, percent change, recent SEC filing count, and insider ownership filing count, plus counts of checks requested and completed.
