Tools

• check_contrast

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

  shallow
• 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.

  shallow
• detect_code

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

  shallow
• 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.

  shallow
• generate_clamp

  Calculate a fluid CSS clamp() expression for responsive sizing between two viewport widths. Pure calculation — returns a CSS snippet, writes and stores nothing.

  shallow
• get_color_shades

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

  shallow
• get_font

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

  shallow
• 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.

  shallow
• get_font_files

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

  shallow
• 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.

  shallow
• get_palette

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

  shallow
• get_scss_mixin

  Get one SCSS mixin by id: full source, parameters and usage example.

  shallow
• list_code_converters

  List available code converters with their from/to ids and per-converter option schemas.

  shallow
• list_scss_mixins

  List the SCSS mixin catalog (id, title, short description), optionally filtered by group or search.

  shallow
• list_svg_presets

  List the available SVG optimization presets and what each one does.

  shallow
• 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.

  shallow
• 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.

  shallow
• optimize_svg

  Optimize/clean SVG markup (SVGO). Pure markup transformation — nothing is executed or stored. Returns minified SVG plus before/after sizes. Rate limit: 30 calls/min per IP.

  shallow
• 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).

  shallow
• 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.

  shallow
• search_palettes

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

  shallow
• svg_to_datauri

  Encode an SVG (or fetched image) as a CSS-ready data: URI. Provide either raw svg or a url. Rate limit: 30 calls/min per IP.
