How do I find my Brand.dev API Key?

Log in to your [**Brand.dev dashboard**](https://brand.dev/), and you will find your API Key in the 'API' section. Copy and paste it below.

What is the difference between NAICS and SIC?

SIC is the older classification system, while NAICS is the modern standard used by North American statistical agencies. Both provide hierarchical metadata for industries.

Can the agent show industry descriptions?

Yes. The `get_classification_details` tool retrieves the official title and detailed description for any valid classification code.
