{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"Am I billed for failed requests?","acceptedAnswer":{"@type":"Answer","text":"No. You are not billed for failed requests or requests where we are blocked (rarely happens). Credits are only consumed on successful responses."}},{"@type":"Question","name":"How does the Font API detect fonts on a website?","acceptedAnswer":{"@type":"Answer","text":"The API renders the page in a headless browser, then walks the computed style tree to read the actual fontFamily applied to headings, body, and UI elements. It also parses @font-face declarations, link tags to Google Fonts / Adobe Fonts, and @import rules — so the response reflects what users really see, not just what is declared in the source CSS."}},{"@type":"Question","name":"What font information does the API return?","acceptedAnswer":{"@type":"Answer","text":"Each response includes the primary font family for body text and headings, fallback stacks, weight and style variants in use, the source (Google Fonts, Adobe Fonts, self-hosted, or system font), and usage context (heading vs paragraph). The output is structured JSON ready to drop into a design tool or branded template."}},{"@type":"Question","name":"Can the API identify what font a website uses?","acceptedAnswer":{"@type":"Answer","text":"Yes — Context.dev is the programmatic equivalent of \"Inspect → fontFamily\" for any domain on the public web. Pass a URL, get back the heading and body font names. We resolve the rendered font, not just the first item in the CSS stack."}},{"@type":"Question","name":"What happens with custom or proprietary fonts?","acceptedAnswer":{"@type":"Answer","text":"When a brand uses a licensed custom font that isn't publicly distributable, the API returns the font name plus a publicly available alternative (similar style and metrics) so you can still render branded UI without breaching the original license."}},{"@type":"Question","name":"Does the Font API work for Google Fonts and Adobe Fonts?","acceptedAnswer":{"@type":"Answer","text":"Yes. Google Fonts, Adobe Fonts (Typekit), Bunny Fonts, and self-hosted webfont CDNs are all detected. The \"source\" field in the response tells you exactly where the font is loaded from so you can replicate the embed."}},{"@type":"Question","name":"Is the Font API free?","acceptedAnswer":{"@type":"Answer","text":"Yes — work-email signups get 500 API credits at 30 req/min, enough for 50 full font-and-brand lookups; free-email signups get 250 credits at 10 req/min. A single API key also unlocks Logo, Colors, Styleguide, and the rest of the Context.dev brand-data suite."}}]}
