2. 22

   We read the SEC's filing list

   The company is found in the SEC's list of registered companies, and its filings of the last 12 months are read from the SEC's public filing database.

   Read the answer

   You see how many 8-Ks the company filed and the newest ones, each with its date, a plain label and a link to the filing.

Bulk 8-K lookups run the same search on a whole list with one CSV file.

The free tool looks up one company at a time. With a 1Lookup account you upload a CSV file in the dashboard, pick the column that holds the tickers, names or CIK numbers and download the same file back with the result columns filled in on every row. These rows are invented.

• 2 credits for each company that filed at least one 8-K in the window, and nothing for a company that filed none, a name the SEC does not list or a name that fits several companies.
• Up to 2 million rows in one CSV file.
• Up to 200 API requests per 10 seconds for each API key, and each account can make up to 1,000 requests a minute in total across all its keys.

The 8-K Event Lookup API returns the same list as JSON from one request.

Send a ticker, a CIK number or a company name to the endpoint with your API key. A company that filed at least one 8-K in the window costs 2 credits, and a company that filed none, a name that matches nothing or a name that fits several companies costs 0. Which of these it was is in classification.outcome.

To look up every company on a list from your own software, see our 8-K Event Lookup API.

• Item numbers become plain words.

  An 8-K lists numbers like 5.02 and 2.02. Each newest filing shows what that number means, such as an executive or director departure or appointment.

• Every filing links to the original.

  Each row opens the filing on the SEC's own site, so you can read what the company actually said.

• A ticker, a name or a CIK number all work.

  A CIK number finds a company that no longer trades and so has no ticker. A name that fits several companies lists them so you can pick one.

• A quiet company gets a plain answer.

  A company that filed no 8-K in the year, a private company or a typo returns a clear sentence saying so, not an empty page.
