Search the Fontsource catalog of 2000+ open-source fonts. The fuzzy query matches id and family (exact, then prefix, then substring, then all words). Filters are AND. Rows are compact and carry the id every other tool needs. Filters without a query browse a category.

Metadata for one font: subsets, weights, styles, variable axes, unicode ranges, license, npm package names, CSS font-family names, fontsource.org page, zip URL, and CDN URL templates for every file. Call it before get_font_css or download_font to learn which subsets and weights exist.

Font embedding snippets: CDN tags, @import lines, npm install and import lines, the font-family rule, and the @font-face CSS text with absolute URLs, safe to inline. Defaults to weight 400 normal. Each extra weight and style combination adds about 1.5KB of CSS. Set variable:true for the variable package; the font-family then becomes " Variable".

Download font files to disk under //. Default dest is $FONTSOURCE_DOWNLOAD_DIR, else ./fonts (currently /app/fonts). Static mode filters subsets, weights, styles, and format. variable:true fetches --.woff2 variable files and ignores weights and format. zip:true saves the official all-files zip without extracting it. Returns saved names and bytes.

Catalog facets: counts per category, subset, license, type, and variable or static. With outFile it also writes the full 2000+ font catalog JSON (id, family, subsets, weights, styles, category, license, type, variable) to that path so you can grep or jq it locally instead of paginating search_fonts.

Variable-font axis registry: name, description, min, max, and default for every axis tag (wght, wdth, opsz, slnt, ital, GRAD, and the rest). Pass a tag for one entry.
