Tools (15)

  • search_fonts

    Search the free font catalog by name, category, style tags, language coverage, variable/monospace flags and style count. Returns a paginated list of families.

  • recognize_font

    Identify which font is used in an image. Powered by our OWN CNN embedding model, trained on the jinero font catalog — it matches fonts by visual shape/style, so it needs NO OCR and NO text (works for Latin and Cyrillic). Send a tight crop of one line of text as either image_url (public URL) or image_base64 (base64/data-URI, e.g. a local screenshot). The image is processed in memory and deleted immediately — never stored. Returns the most visually similar font families with scores. Typically 0.3-1.7 s (an OCR-assisted rerank of top candidates engages when retrieval is uncertain). Rate limit: 5 calls/min per IP (model inference is compute-heavy).

  • get_font

    Get full metadata for one font family by slug: styles, weights, axes, license, subsets and download/CSS URLs.

  • get_font_files

    List every font file (weight/italic/format + direct woff2/ttf URL) for a family — handy for building custom @font-face rules.

  • get_fonts_css

    Generate ready-to-use @font-face CSS for a family spec (Google-Fonts-compatible), e.g. "inter:wght@400,700" or a variable range "inter:wght@300..900". Returns CSS text.

  • get_font_download_url

    Return the direct ZIP download URL for a font family (all styles + a ready fonts.css). Does NOT download — hand the URL to the user or fetch it separately.

  • check_contrast

    Check the WCAG contrast ratio between a foreground and background color, with AA/AAA pass/fail for normal and large text.

  • get_color_shades

    Generate tints and shades for a base color (lighter/darker steps) with hex values.

  • name_color

    Get the closest human-readable name for one or more colors. Pass a single hex or several comma-separated (e.g. "#3b82f6,#000,#ff7f50"); returns each input with its nearest color name, the reference hex, an exact-match flag and the perceptual distance.

  • extract_colors

    Extract a dominant-color palette from an image. Send either a public image_url or image_base64 (base64/data-URI, e.g. a local screenshot). The image is processed in memory and never stored. Each color comes back with its hex, rgb, hsl, share of the image, and the closest human color name — a named palette in one call. Rate limit: 10 calls/min per IP.

  • search_palettes

    Search the color-palette catalog by name, tone, temperature, mood, harmony, exact color count and tags. Returns a paginated list.

  • get_palette

    Get one color palette by id: its colors (hex), name/derived title, mood, harmony, temperature and tags.

  • minify_code

    Minify or beautify JS, CSS, HTML, SVG, JSON or XML text. Set type=auto to sniff the language. The code is only parsed and re-printed — never executed and never stored. Rate limit: 30 calls/min per IP.

  • detect_code

    Detect the language/format of a code snippet. Static analysis only — the snippet is never executed and never stored.

  • convert_code

    Convert code between text formats (e.g. JSON↔YAML, CSS↔SCSS). Pure text transformation: the source is parsed and re-serialized, never executed and never stored. Use list_code_converters for valid from/to ids and per-converter options. Rate limit: 30 calls/min per IP.
