This is a simple and efficient CLI written in Go to lookup the Central Index Key (CIK) numbers of companies from the SEC database. Enter a company name, and it will return the associated CIK number.

• Handles gzip-compressed responses
• Extracts CIK and company name from the response
• Parses multi-word company names

• Go v1.20
• goquery package (used for HTML parsing)

git clone https://github.com/nronzel/cik-lookup.git
cd cik-lookup

Install Dependencies

go mod tidy

To use the tool, run the following command from the terminal:

go run main.go <company_name>

Replacing the company name with the company you want to look up.

Example:

go run main.go microsoft corp

The results are truncated to 100 if more than 100 results are found. Try being more specific in these situations.

Simple POST request with the company name to the SEC CIK lookup URL.
