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 company name, a list of filings each with insider name, roles (e.g. officer, director), and an array of transactions — each transaction includes a code (e.g. S for sale, P for purchase), number of shares, price per share, and a human-readable meaning of the transaction code. Returns up to a configurable number of results.
Example use cases
Executive selling alert for hedge fund
“Show me all open-market sales by NVIDIA insiders — I need the insider names, their roles, how many shares they sold, and at what price.”
Due diligence before earnings
“Before I invest, can you grab the recent insider transactions for Tesla from Signal Nodus so I can see if directors or officers have been quietly unloading shares?”
Corporate governance research
“I'm writing a report on insider activity at major semiconductor companies — can you pull the latest Form 4 transaction data for AMD, including who traded and whether they were buying or selling?”
Technical details
Endpoint
GEThttps://api.signalnodus.ai/v1/insiderWhen to prefer
Choose this endpoint when you need structured, parsed insider transaction data from SEC Form 4 filings without having to scrape or parse raw EDGAR XML yourself. It is particularly useful for financial research agents, equity analysts, or compliance tools that need to quickly surface who inside a company is buying or selling shares and at what price. Prefer this over raw EDGAR access when you want clean JSON output pinned to specific accession numbers.
Side effects
- Company not found in SEC EDGAR — returns empty filings array
- Invalid or unrecognized ticker/company name — may return no results
- Rate limiting or payment failure (x402) — payment required error
- Accession number mismatch — stale or incorrect pinned filing reference
- No recent Form 4 filings on record — returns empty transactions list
