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).
Example use cases
Due diligence before buying a penny stock
“I'm thinking about buying shares of MMAT — can you check if their most recent 10-K has any going concern warnings or substantial doubt language from the SEC filing?”
Portfolio risk scan for distressed holdings
“Pull the going concern status for BIOR from its latest SEC filing — I want to know if auditors flagged any doubt about it continuing as a going concern, and grab the relevant excerpt.”
Short-seller research on a target company
“Does NKLA have going concern language in its latest annual report filed with the SEC? I need the exact excerpt and whether substantial doubt was raised.”
Technical details
Endpoint
GEThttps://filinglane.dev/v1/going-concernWhen to prefer
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.
Side effects
- 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
