BearSignal API — What Your Subscription Includes

Real-time forensic signal feed

Programmatic access to BearSignal's live forensic findings across every U.S.-listed equity (NYSE / NASDAQ, including ADRs) and every Hong Kong-listed equity.

Two signal tiers, clearly labeled

  • Grey flag: BearSignal's engine has detected a hard, self-contradicting disclosure within a company's own filings. A signal pending confirmation.
  • Red flag: a higher-confidence assessment where BearSignal's reasoning layer has further corroborated the contradiction across multiple sources.

Every signal is delivered with its tier explicitly labeled. Neither a grey flag nor a red flag is a final report, a verdict, or a statement that fraud or wrongdoing has occurred — both are assessments pending further confirmation.

Court-grade evidence chains

Not raw data. Cross-filing evidence synthesized into structured, fully-sourced chains you can act on and audit.

Institutional coverage, one endpoint

Regulatory filings, corporate-registry penetration, ownership and relationship mapping, and insider-transaction signals — integrated into a single judgment, delivered via API.

Live status updates — append-only, never retroactively rewritten

Signals update as their status evolves. A subscription is a feed of evolving assessments, not a static report archive.

A signal you have already received never disappears from the feed. When an assessment is downgraded, superseded, or withdrawn, you receive a new event carrying the new statusactive, downgraded, superseded or retracted, with the timestamp of the change. We do not silently remove entries, and we do not edit history you have already been served.

Every subscriber receives the same content at the same time

All subscribers receive identical signal content simultaneously. Subscription level does not determine how early you see a name, and there is no staggered or delayed release between subscribers.

Your entitlement is enforced server-side, and nothing within it is withheld: we do not store any per-subscriber setting that would cause you to miss an item you are entitled to. Query filters, when offered, are stateless request parameters — they never alter your entitlement, and the full set is always retrievable.

Access & limits

  • Rate limit: 60 requests / minute per key.
  • Full history: query all historical signals and their complete status-change history for as long as your subscription is active.
  • Incremental delivery: each event carries a monotonic sequence number; resume from your last cursor and no event is skipped.
  • Availability: provided on a commercially reasonable basis.

How BearSignal Works

BearSignal does not rank statistical anomalies. It applies an absolute-contradiction test: do a company's own disclosures logically contradict one another?

  1. Detect. A five-dimension forensic engine scans every covered company's own filings for hard internal contradictions — deterministic and fully explainable.
  2. Grey-flag. When a contradiction is found, the company is grey-flagged: a hard contradiction detected, pending confirmation.
  3. Corroborate → red-flag. BearSignal's reasoning layer tests the contradiction against multiple independent sources. When it holds, the signal is elevated to a red flag — a higher-confidence assessment, still pending final confirmation.
  4. Build the chain. Evidence is synthesized across filings into a court-grade, fully-sourced chain — often before a company formally restates.

Neither a grey flag nor a red flag is a verdict or a final report. Both are assessments that evolve as evidence accumulates.

Coverage: all U.S.-listed equities (NYSE / NASDAQ, including ADRs) and all Hong Kong-listed equities.

Important Disclosures [DRAFT — subject to legal review before launch]

BearSignal publishes forensic research and opinion. It is not investment advice, and nothing provided is a recommendation or solicitation to buy, sell, or hold any security.

BearSignal signals are graded as "grey flags" and "red flags." A grey flag means BearSignal's engine has detected internally inconsistent or self-contradicting disclosures within a company's own public filings. A red flag means that contradiction has been further corroborated across multiple sources. In all cases, a signal is an assessment pending further confirmation — it is not a final report, a conclusion, an allegation, or a statement that any company or individual has engaged in fraud or wrongdoing.

BearSignal, its affiliates, principals, and clients may hold short positions in, or otherwise profit from declines in, the securities covered.
