## 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 filinglane-going-concern-check-cf46a319
```

Example prompt: Check whether SPCE has any going concern or substantial doubt language in its latest SEC 10-K filing and give me the relevant excerpt.

## When to prefer this

Use this endpoint when you need a fast, targeted extraction of going concern language from a specific company's SEC filing without downloading or parsing the full filing yourself. Ideal for AI agents doing due diligence, portfolio risk screening, or short-seller research where a structured boolean flag plus cited excerpt is more useful than a raw document. Prefer this over full-filing dump services when you only need MD&A-level going concern signals and want quality-gated, citation-backed results at low per-call cost.

## Known failure modes

- 422 Unprocessable Entity when filing quality grade is C or below — no charge applied
- Ticker not found or not publicly traded on SEC EDGAR
- No going concern language detected (going_concern: false) — valid response, not an error
- Invalid or mismatched accession number provided
- Rate limiting or payment failure via x402 USDC micropayment

## How this service works

**RESHAPE wedge:** SEC **MD&A (`mda`)** + common **8-K items** → quality-gated markdown with `sourceUrl`, cache HIT/MISS ($0.05/$0.01), and x402 receipts. `risk_factors`/`business` available as secondary (Massive already sells those ~$0.01). Not a full-filing dump. Base USDC (`eip155:8453`) Exact; grade C → 422 no charge. Not financial advice. FilingLane is not affiliated with the U.S. Securities and Exchange Commission (SEC). Data sourced from publicly available EDGAR filings.

## Output

Returns a JSON object containing: a boolean 'going_concern' flag, a boolean 'substantial_doubt' flag, an 'excerpt_md' with the relevant markdown text from the filing, a 'cite' object with the SEC form type, accession number, and direct SEC URL, the ticker symbol, and a 'source' field indicating whether the data came from MD&A, 8-K, or both. Only returned if the filing passes quality gate (grade below C returns a 422 with no charge).
