`edgar_ticker_to_cik`

Pack: edgar · Endpoint: https://gateway.pipeworx.io/edgar/mcp

Resolve a US stock ticker (e.g. “TSLA”) to the SEC’s 10-digit CIK identifier — required by every other SEC tool. Call THIS FIRST when you have a ticker 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}. Cheap, no rate limit concerns. Most other tools also accept tickers directly and call this internally — only use it explicitly when you want the CIK as data.
