What it does

Resolves a stock ticker or company name to its SEC Central Index Key (CIK), returning the closest matching companies, each with its ticker, name, and 10-digit CIK. The CIK is the identifier the other tools require.

Primary use cases

Finding a company's CIK from its ticker (e.g. AAPL) before requesting filings or financials.
Validating a company name against the official registry.

Good to know

Pass the ticker or company name as query. The returned cik is already 10-digit zero-padded (e.g. 0000320193), ready to hand to the other tools.
