## 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 agent402-dossier-us-stock-due-diligence-report-08dfcd5f -d '<json body>'
```

Example prompt: Pull me a full due-diligence dossier on NVDA — I want it in markdown and focus on litigation and debt risks.

## When to prefer this

Choose this endpoint when you need a single-call, AI-synthesized due-diligence report on a US public company that aggregates SEC 10-K, 10-Q, 8-K, insider filings, and web signals into one structured document. Prefer it over raw SEC EDGAR queries when you want an analyst-style narrative with citations rather than raw filing data, and over general web search when you need structured financials alongside qualitative analysis. Best for investment research, portfolio review, risk assessment, and M&A screening workflows where depth and source citation matter.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result
- Ticker not listed on a US exchange may not have SEC filings available
- SEC EDGAR data lag may mean very recent filings are not yet indexed
- Focus array exceeding 8 items may be ignored or truncated
- Network or upstream SEC/web fetch failures may reduce source count or return partial dossiers
- Format enum values other than 'markdown' or 'json' will be rejected

## How this service works

Hand over a ticker and get one due-diligence dossier back. Pulls the company's SEC EDGAR filings (10-K / 10-Q / 8-K) and Form 4 insider trades, a live quote, and grounded web research on recent developments and risks, then synthesizes a ~2,400-word cited dossier - business, financial posture, insider activity, red flags, and a balanced diligence read. Grounded in real SEC data, not a generic web guess. One payment, one report. USDC (x402/MPP) or card (Stripe). Not cached.

## Output

Returns a structured report containing: a metadata object (ticker, company name, filing counts, sources cited, synthesis model), a markdown or JSON dossier narrative with inline citations, XBRL-sourced financial tables (revenue, quarterly figures), insider filing summaries, and a numbered sources list with URLs to SEC EDGAR filings and web references.
