Jinero

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

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 imm

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

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

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.

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

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

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

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

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

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.

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

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.

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.

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

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

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

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