#avatar

Extract initials and avatar monograms from a name or phrase. The initials endpoint returns the first letter of every significant word — automatically skipping lower-case nobiliary and linking particles (van, von, de, della, la, der, of, the…) so "Ludwig van Beethoven" gives LB and "Charles de Gaulle" gives CG — with options for a separator between letters, a dotted form (J.D.), upper-case or original case, and a maximum number of initials. The monogram endpoint returns the short one-, two- or three-letter badge initials used for UI avatars and chips, taking the first and last significant words ("John Michael Doe" → JD) and falling back to the leading letters of a single name. Everything is multibyte-safe, so accented and non-Latin letters (José María → JMA) work correctly. Ideal for default avatars, contact chips, initials badges, monogram graphics, document headers and mail-merge. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This produces the initials text; to render them as an avatar image use an avatar API.

Turn an email address into its Gravatar avatar and public profile. Pass an email and the service normalises it, computes the MD5 and SHA-256 hashes Gravatar uses, builds a ready-to-use avatar URL, checks whether a custom Gravatar actually exists, and fetches the public profile when present — display name, username, profile URL, location, about text, linked accounts and photos. A dedicated avatar endpoint builds just the image URL with full options: size (1-2048), a default image (identicon, monsterid, robohash, retro, mp, blank, 404, or your own URL), rating and force-default. Ideal for user-profile enrichment, comment systems, contact cards, team pages and onboarding — showing a real avatar from nothing but an email. A Gravatar lookup — distinct from deterministic avatar/identicon generation (avatar), which renders a brand-new image from a seed rather than fetching the avatar a person actually chose. No upstream key, no cache.

Generate deterministic avatars and identicons from any seed — the same seed always renders the exact same avatar, so user IDs, usernames or emails map to stable, unique profile pictures with no storage. 30 art styles (bottts robots, pixel-art, avataaars, identicon, lorelei, notionists, fun-emoji, shapes, rings and more), returned as ready-to-use SVG markup or a base64 PNG data-URI, with options for size, corner radius, background colour and flip. Backed by DiceBear. Ideal for default user avatars, comment/forum placeholders, dashboards, game characters, test fixtures and any UI that needs an instant, reproducible profile image.

A fast, fully-local SVG generator for mockups and UIs: placeholder images (a sized rectangle with centered text and automatic contrast), initials avatars (with a deterministic colour derived from the name, in a circle or square), and identicon-style symmetric patterns generated deterministically from any seed. Every endpoint returns the JSON envelope or, with raw=1, the raw SVG so the URL can be used directly as an image source. Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for prototypes, dashboards, user avatars, empty states and design systems.
