The SEC CIK number for a stock ticker or company name, from EDGAR’s company list.

Tool description as the model sees it

Resolve a US stock ticker (e.g. “TSLA”) OR a company name (e.g. “Tesla”, “Apple Inc”) to the SEC’s 10-digit CIK identifier — required by every other SEC tool. Call THIS FIRST when you have a ticker/name and need to use edgar_company_concept, edgar_company_filings, edgar_company_facts, sec_8k_recent, or any other SEC-keyed tool. Returns {cik, cik_padded, company_name, ticker, matched_by}; when matched by name it also returns alternatives — up to 3 OTHER companies whose names also matched, one per distinct CIK, with the winner’s OWN share classes/tickers excluded (never listed as its own alternative). Use alternatives to tell a genuinely CONTESTED name match (a real rival company also matched) from a clean one (nothing else did). Cheap, no rate limit concerns. Most other tools also accept tickers/names directly and call this internally — only use it explicitly when you want the CIK as data. The response carries a next hint: the usual NEXT step after resolving is edgar_company_snapshot({ticker_or_cik}), which returns the recent filings list AND the headline XBRL financials in one call — do not chain edgar_company_filings then edgar_company_concept by hand to get that.

Parameters

Name	Type	Required	Description
`ticker`	string	no	REQUIRED (or one of its aliases `ticker_or_cik` / `company`). Stock ticker symbol (e.g., “AAPL”, “MSFT”, “TSLA”) or company name (e.g., “Apple”, “Microsoft”)
`ticker_or_cik`	string	no	Alias for `ticker` — the spelling edgar_company_filings and edgar_insider_transactions use. A ticker or company name; this tool RESOLVES to a CIK, so passing a bare CIK has nothing to look up.
`company`	string	no	Alias for `ticker` — use it when what you have is a company NAME (“Apple Inc.”) rather than a symbol. Same argument, same behaviour.
