brand.json

Machine-readable brand identity for the agentic advertising era

A standard file at /.well-known/brand.json that tells AI agents who your brand is, what it looks like, and how it wants to be represented in advertising.

Why brand.json?

AI agents need structured brand data to make advertising decisions — colors, tone, portfolio structure, category preferences. Without a standard, every platform asks for this differently. brand.json provides a single source of truth that any agent can discover and consume automatically.

What it includes

Brand Identity

Name, description, logos, colors, and typography. Everything an agent needs to represent your brand correctly.

Portfolio Structure

Define your brand architecture: master brands, sub-brands, endorsed brands, and their relationships.

Advertising Preferences

Categories, restrictions, tone guidelines, and audience targeting preferences that agents should follow.
