  title: CharacterQuilt Brand Profiles Branding API
  version: '1.0'
  description: Public, machine-readable brand-profiles data surface published by CharacterQuilt. Each catalogued company exposes an HTML page at /branding/{slug} and a JSON profile at /branding/{slug}.json containing a branding extraction — color scheme and palette, typography and font stacks, spacing, component styles, imagery, personality, and design-system signals — extracted from the company's live website. Intended for agents, designers, and AI tools. Read-only and unauthenticated. Discovered via /llms.txt. Not an official specification.
