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
A JSON object containing the manager's name, CIK, reporting period, accession number, total portfolio value in USD, and a ranked array of holdings. Each holding includes the issuer name, CUSIP, FIGI (if available), value in USD, share count, share type (e.g. SH), put/call indicator, security class title, and the accession number. Results are ordered largest-value-first, with a configurable limit up to 500 positions.
Example use cases
Hedge fund portfolio transparency check
“What does the fund with CIK 1067983 currently hold according to its most recent 13F? Give me the top 50 positions by value with CUSIP and share count.”
Quarterly portfolio change analysis
“Fetch the 13F holdings for manager CIK 0001709323 for the period ending 2025-09-30 so I can compare it against their December quarter positions.”
Institutional ownership research for a stock
“I'm researching which big funds own CoStar Group — can you pull the latest 13F for manager CIK 0001566307 and show me whether they hold CUSIP 22160N109 and how many shares?”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/13f/managerWhen to prefer
Choose this endpoint when you need structured, ranked institutional holdings data directly from SEC 13F-HR filings for a specific manager identified by CIK. It is ideal for portfolio research, institutional ownership analysis, fund transparency checks, or building datasets of large investor positions. Prefer it over general SEC EDGAR search when you want pre-parsed, value-sorted holding rows with CUSIP/FIGI identifiers rather than raw XML filings. It is particularly useful when you already know the manager's CIK and want clean, machine-readable output without parsing EDGAR directly.
Side effects
- Invalid or non-existent CIK returns an error or empty result
- CIK belongs to a filer that has never submitted a 13F-HR filing
- Requested period date has no matching filing, returns null or empty holdings
- Malformed CIK format (non-numeric or >10 digits) triggers validation error
- Rate limiting or payment failure for the $0.02 USDC per-call fee blocks the request
- FIGI field may be null if the security cannot be mapped to a Financial Instrument Global Identifier
