How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with a 'result' field containing the 13F filing data (holdings, positions, filer details) and a 'success' boolean indicating whether the lookup succeeded. The result structure reflects SEC EDGAR filing contents for the matched manager and quarter.
Example use cases
Research fund's quarterly equity positions
“What stocks did Renaissance Technologies report holding in their most recent 13F filing? I want to see their latest quarterly positions.”
Retrieve filing by specific accession number
“I have a specific SEC accession number for a 13F filing — 0001234567-23-000456 — can you pull the holdings data from that filing for CIK 1234567?”
Compare historical 13F holdings for a given quarter
“Get me the 13F institutional holdings for Citadel Advisors for the quarter ending 2023-09-30 so I can see what they were holding at that point in time.”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/holdings/filing?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured 13F institutional holdings data from SEC EDGAR and want a simple paid API rather than scraping EDGAR directly. Prefer this over raw EDGAR queries when you need quick lookup by manager name (CIK resolution included) or when accessing historical quarterly filings by accession number. Not suitable for real-time market data, non-13F filings, or non-US regulatory filings.
Side effects
- CIK not found or invalid — returns success:false or empty result
- Manager name ambiguous — best-effort resolution may match wrong entity; prefer CIK
- Accession number requires CIK to be supplied together
- Quarter not yet filed or data unavailable — returns no result
- Malformed quarter date format — must be ISO YYYY-MM-DD
- Rate limit or payment failure — 402 response requiring USDC micropayment
