## 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 capitalspec-sec-filing-analyst-2a056c5b -d '<json body>'
```

Example prompt: I'm looking at NVDA — can you fact-check the claim 'NVIDIA's data center revenue now accounts for more than 50% of total revenue' against their actual SEC filings and tell me if the filings support, undercut, or give mixed signals on that?

## When to prefer this

Choose this endpoint when you need primary-source verification of a specific claim or thesis against actual SEC-filed documents rather than news summaries, analyst opinions, or LLM-generated financial data. Ideal for due diligence workflows, equity research validation, short-seller report auditing, or any scenario where verbatim regulatory disclosure evidence is required. Prefer over general financial data APIs when the user needs a graded, evidence-backed verdict rather than raw numbers.

## Known failure modes

- Ticker not found or not publicly traded — returns error or INSUFFICIENT verdict
- Statement too vague for grounding — may return INSUFFICIENT with guidance to refine
- Relevant filings not yet indexed on EDGAR — returns INSUFFICIENT with note on coverage gap
- Async job timeout — job ID may expire before result is fetched
- Payment failure — job not initiated, error returned immediately
- Claim requires real-time data beyond filing dates — verdict limited to disclosed periods

## How this service works

Test an investment thesis or fact-check a claim against a company's actual SEC filings. Send {ticker, statement}; an analyst selects the relevant 10-K/10-Q/8-K from the full EDGAR index, deep-reads them, and returns an evidence-graded verdict — SUPPORTS, MIXED, UNDERCUTS, or INSUFFICIENT — with verbatim quotes, red flags, and what went unread. Async: pay, job id in ~2s, result in ~3 min. Built for due-diligence and equity-research agents.

## Output

An asynchronous result (polled via job ID, ready in ~3 minutes) containing: a categorical verdict of SUPPORTS, MIXED, UNDERCUTS, or INSUFFICIENT; verbatim quotes from the relevant SEC filings; identified red flags or contradictions; the specific 10-K/10-Q/8-K documents consulted; and a note on what portions of the filings went unread.
