Company identity
7 endpointsLook up a company by CIK or ticker, see its securities, and check whether each one is still listed.
Where it comes from- Submissions API and the nightly submissions.zip
- Ticker and CIK list
- Filing archive, one folder per company (Amprius shown)
Names, tickers, and exchanges come from each company's submissions file. The classes of stock, with their trading symbols and exchanges, are listed on the cover page of the 10-K and 10-Q, so you read those too. To learn that a security was delisted or deregistered, you watch for Form 25 and Form 15 filings.
