How this service works

Signal Nodus: year-over-year diffs of SEC filing sections, pinned to accession numbers. The diff is the product; raw data is the on-ramp.

Output

A JSON object containing the fund manager's name, an array of holdings (each with issuer name, USD value, and portfolio percentage), and a count of distinct issuers in the filing.

Example use cases

Hedge fund portfolio snapshot

“Show me all the current 13F holdings for Bridgewater Associates — list every issuer, the USD value of each position, and its share of the total portfolio.”

Concentration risk check

“How concentrated is ARK Invest's portfolio? I want to see each holding and its percentage weight so I can tell if they're too exposed to any single stock.”

Competitor fund benchmarking

“Pull the 13F holdings for Renaissance Technologies and tell me how many distinct issuers they hold and what the top positions are by dollar value.”

When to prefer

Choose this endpoint when you need structured, parsed 13F institutional holdings data tied to specific SEC accession numbers, with portfolio weights pre-calculated. It is preferable over raw EDGAR scraping when you need clean JSON output without parsing HTML or XBRL yourself, and when you want year-over-year diff context alongside point-in-time snapshot data.

Side effects

Unknown or misspelled manager name returns empty or error response
Manager has not filed a 13F (not required for funds under $100M AUM)
Filing data may lag SEC reporting deadlines by days or weeks
Invalid CIK or accession number returns a 404 or empty dataset
Rate limiting or payment failure returns a 402 response requiring USDC payment
