How does the Font API detect fonts?

The API scans CSS files, inline style blocks, web font imports (@import, link tags), @font-face declarations, and common font usage in text-heavy elements to detect and categorize fonts by role.

What font information is provided?

The API returns primary and fallback font families, font weights and styles, font sources (Google Fonts, Adobe, self-hosted), usage context (headline, body, UI), and similar font alternatives for protected custom fonts.

What if a company uses custom protected fonts?

For companies using custom fonts protected by terms of service, the API returns the most similar publicly available font alternative in the response.
