Each recipe gives you something you can run today. The example responses are shortened samples, so dates and numbers will differ when you run them.

Recipe 1: insider buys this week

Needs: a Free key. Costs: 3 units a call. Insiders such as executives and directors must report their open-market trades on SEC Form 4. This pulls the buys filed in the last 7 days.
A sample filing from the response. This one is a sale, shown for its shape. With side=buy, every filing is a buy.
How to read it:
  • side is the filing’s main direction by dollar value.
  • plan10b5_1 means the trade followed a pre-set schedule. It says less than a trade the insider chose on the day.
  • filedAt is the filing date. The trade date is inside trades.
  • A Free key returns the 5 newest filings from the last 90 days and no more pages. A Pro key pages through 365 days with limit and cursor. See Conventions.
  • An empty list means no open-market trade is on file. It does not mean nobody filed.

Recipe 2: which funds hold a stock

Needs: a Pro key. Costs: 3 units a call. 13F filings show what big funds held at the end of each quarter. Start from a stock, then look at one fund’s changes.

See what one fund changed

Use the cik from the step above.
A sample change from the response:
Read these with care:
  • period is the quarter end. The filing is public up to 45 days later. This is not what the fund holds today.
  • The holders list covers the funds we track, not every investor. An empty list does not prove nobody holds the stock.
  • approxTradeValueUsd is an estimate from quarter-end prices. It is not a price anyone paid, and nothing inside the quarter is visible.

Recipe 3: the latest 8-K, in an AI chat

Needs: no key. Works in Claude or ChatGPT with the research connector added. Paste this into a new chat:
Behind the scenes the assistant calls get_company_disclosures with ticker set to NVDA. A sample of what comes back:
Good follow-ups to ask:
  • “Which of these was the earnings release?” The item 2.02 is the earnings result.
  • “Compare this with the insider trades in the same weeks.” This one calls a second tool, so ask it in the same chat.
An 8-K item number alone does not tell you what happened. Always open the linked filing before you act on it.
