Short answer

How do I find a company's CIK or legal name if I only have a partial name?

Your AI uses the search_companies tool to find matches in the SEC EDGAR database. It returns the official legal name and CIK number for the entities it finds. You'll see the specific identifiers you need to move forward.

The results you get

Precise company data

Your agent turns vague names into official SEC records.

IDENTITY

Official legal names

The AI finds the exact registered name for an entity. This ensures you aren't working with a nickname or an incorrect abbreviation.

INDEXING

Unique CIK numbers

Your agent pulls the Central Index Key for the matched company. You can use this number to pull specific filings later.

MATCHING

Partial name lookups

The AI handles fuzzy searches when you don't have a full name. It scans the EDGAR database to find the closest matches.

DECISION

Human verification

The AI presents a list of potential matches. You have to look through the results and pick the right company.

FAQ

How this task behaves

    Will the AI automatically pick the right company if there are multiple matches?

    No. The AI provides the list of matches, but you must verify and select the correct one.

  • 03

    Can I use this to find private companies?

    No. This tool only searches for entities registered with the SEC.

  • 04

    Can the AI update or change company information in the SEC database?

    No. The AI can only read and retrieve existing data. It cannot modify any SEC records.

  • 05
