How this service works
AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.
Output
Returns a JSON object with the queried auditor name, an as-of timestamp, total filing matches, a count of matched companies, and an array of company records each containing the CIK, company name, number of filings matched, form types (e.g. 10-K), the latest filing date, and matched text snippets. Includes a disclaimer note about text-mention proxy methodology.
Example use cases
Auditor concentration market share analysis
“Show me all public companies that named 'Deloitte & Touche LLP' in their 10-K filings over the past two years — I want to understand how dominant they are and which registrants they audit.”
Shared auditor network for due diligence
“I'm doing due diligence on a company and want to know what other public companies share their auditor, 'Grant Thornton LLP' — pull up to 100 companies from the last 400 days of annual reports.”
Auditor switching and recent engagement detection
“Which companies have named 'BDO USA LLP' in their annual reports in the last 90 days? I'm tracking recent auditor engagements and want the latest filing dates for each registrant.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/graph/auditorWhen to prefer
Use this endpoint when you need to identify which SEC-registered public companies are audited by a specific firm, based on full-text search of 10-K filings on EDGAR. Prefer this over generic EDGAR search when you want structured, aggregated results per registrant with filing counts, or when you need to map auditor concentration or shared-auditor networks in a single call. Best suited for financial research, governance analysis, audit market studies, or due diligence workflows.
Side effects
- Audit firm name too short (< 3 characters) returns validation error
- Name not found in any filing returns empty companies array with count 0
- lookback_days outside 30–1825 range returns parameter validation error
- limit outside 1–100 range returns validation error
- False positives possible: auditor name mentioned in non-auditor contexts (predecessor auditor, litigation references) as noted in response disclaimer
