Short answer

How can I use my AI to audit company metadata?

Your AI uses Polygon.io to fetch industry codes and business descriptions for any ticker you provide. It compares these live details against your own records to find mismatches or missing info. You'll get a clear breakdown of what's correct and what needs your attention.

Audit outcomes

Where your data lands.

The AI categorizes every ticker based on how well its metadata matches your records.

MATCHED

Verified ticker data

The AI confirms the industry and description match your list. These tickers are ready to use without further review.

MISMATCH

Data discrepancies

The AI flags tickers where the industry or description doesn't align with your records. You'll need to check these manually.

MISSING

Incomplete metadata

The AI finds tickers in your list that have no corresponding data in Polygon.io. This shows you exactly where your data is thin.

HUMAN

Manual review required

The AI identifies tickers with ambiguous or conflicting classifications. You decide how to handle these edge cases.

The workflow

What your AI does when the data arrives.

Your agent handles the heavy lifting of fetching and comparing market data.

  1. Identify tickers

    The AI scans your input to find the specific symbols that need auditing.

    list_tickers

  2. Fetch profiles

    get_company

  3. Compare details

    The AI checks the fetched metadata against the information in your files.

  4. Flag errors

    The AI compiles a list of tickers that failed the validation check.

FAQ

How this task behaves

  • 01

    Can the AI update my database with the new metadata?

    No. The AI only reads data from Polygon.io to identify differences. You must manually update your own databases.

  • 02

    Can the AI delete tickers from my spreadsheet?

    No. The AI has no permission to modify, delete, or overwrite your local files.

  • 03

    Does the AI see my Polygon.io API key?

    No. Vinkius manages the connection securely so your AI client never sees your raw credentials.

  • 04

    Can I audit historical industry changes?

    No. The available tools only provide current company metadata.

  • 05

    What happens if a ticker is delisted?

    The AI will report that it cannot find data for that specific ticker in Polygon.io.
