Unicode API

healthy 4,787 Subscribers

The Unicode Character Database (UCD) as an API. Resolve ANY codepoint (0..10FFFF, including the CJK and Hangul ranges) to its name, general category, block and script — plus the literal character, HTML entity (😀), CSS escape and UTF-8/UTF-16 byte sequences. Pass a hex codepoint (e.g. 1F600 → 😀 GRINNING FACE) or a literal character (?char=€). Search 40,000+ named characters by name (e.g. "heart", "arrow"), filter by category or block, and browse all 346 Unicode blocks. Ideal for text-processing tools, emoji pickers, editors, internationalization and developer utilities.

Text Segmentation API

Count and split text the way people actually read it, using Unicode-correct segmentation. The count endpoint returns the number of grapheme clusters — the real, user-perceived characters, so a family emoji counts as 1 (not 7) and an accented letter as 1 — alongside words, sentences, code points, UTF-16 code units (the naive string length that over-counts) and UTF-8 byte length. This is exactly what character-limit fields, tweet/SMS counters and validation need so the count agrees with what the user sees. The segment endpoint splits text into grapheme, word or sentence segments (word segments are flagged word-like versus punctuation and spaces) and is locale-aware, so Japanese, Chinese and Thai word boundaries come out right. Everything is computed locally with no network calls. A Unicode text segmenter — distinct from the Unicode codepoint database (unicode), the case/text-utilities toolkit (text) and string similarity (similarity). No upstream key, no cache.

Emoji API

A complete emoji database in one fast API. Search roughly 1,870 emojis by name, keyword, alias or tag, look up a single emoji by its alias (like rocket or :fire:) or by the emoji character itself, browse any of the nine Unicode categories, or get random emojis (optionally from a category). Every emoji comes with its name, category, aliases, search tags, Unicode code points and the version it was introduced in. Built on the open GitHub gemoji dataset and served entirely in-memory, so responses are instant and the service is always available. Ideal for chat and messaging apps, emoji pickers and search, social and content tools, games and fun widgets.

Genshin Impact API

Genshin Impact game data as an API — every playable character, weapon, artifact set and more from miHoYo's open-world RPG. Look up a character by name (e.g. Albedo → Geo vision, Sword user, 5-star, with title, nation, constellation, birthday, skill and passive talents, and constellations) or pull the full 90+ roster, browse weapons (e.g. Skyward Blade → 5-star Sword) and artifact sets (e.g. Archaic Petra with its 2- and 4-piece bonuses), and list reference categories — elements, nations, bosses, domains, materials, consumables and enemies. Backed by the open genshin.dev dataset. Ideal for team-building and tier-list tools, damage calculators, wikis, Discord bots and any Genshin companion app.

Rick and Morty API

The Rick and Morty universe as an API — every character, location and episode from the show. Look up a character by id or search and filter the roster by name, status (alive, dead, unknown), species, type and gender (e.g. all living Mortys), browse locations by name, type and dimension, or pull episodes by name or episode code (e.g. S03E07 → The Ricklantis Mixup). Each character carries status, species, origin and last-known location, episode appearances and a portrait; locations carry their type and dimension; episodes carry the air date and cast size. Backed by the open rickandmortyapi.com dataset. Ideal for fan sites, trivia and quiz games, Discord bots, learning projects and any Rick and Morty app.
