Localized Names API

healthy 4,616 Subscribers

Get the localized display name of a code in any language — countries and regions, languages, currencies, scripts and calendars. Pass a code, a type and a locale and the name endpoint returns the right name: US as region in fr gives "États-Unis", de as language in fr gives "allemand", EUR as currency gives "Euro", and the same code reads correctly in German, Japanese, Arabic or any other locale. The list endpoint returns every code of a type localized and sorted in that locale's collation — ideal for building a country, language or currency dropdown in any language. Powered by the platform's full ICU data (Intl.DisplayNames) and computed locally with no network calls. Built for internationalised forms and pickers, multilingual UIs, localized reports and onboarding. A localized-names resolver — distinct from country reference data in English (countries), number and currency formatting (numberformat) and locale date formatting (datelocale). No upstream key, no cache.

Writing Systems (ISO 15924) API — oanor API marketplace

Writing Systems (ISO 15924) API

The ISO 15924 register of writing systems — the script codes used by Unicode, BCP-47 and CLDR — served from memory (no key). Every script carries its 4-letter code (e.g. Latn, Arab, Hani), numeric code, English and French names, the Unicode property value alias, the Unicode version it was added in and its date. Look a script up by code or numeric, search by code or name, or list the whole register. 226 scripts. Ideal for internationalization, locale and font tooling, BCP-47 tag validation and text-rendering pipelines.

 Content Negotiation API — oanor API marketplace

Content Negotiation API

HTTP content negotiation as an API. The parse endpoint reads an Accept, Accept-Language, Accept-Encoding or Accept-Charset header — with quality (q) values and parameters — into a clean list ranked by the client's preference. The negotiate endpoint takes that header plus the list of values your server can actually serve and returns the single best match, along with the full ranked result and the entry that matched each candidate. It applies the correct rules for each kind: media-type type and subtype wildcards (text/*, */*), RFC 4647 language-range matching (a request for en matches your en-US, and en-US falls back to en), and exact matching with a * wildcard for encodings and charsets — and a q=0 entry correctly rejects a value. Everything runs locally and deterministically, so it is instant and private. Ideal for i18n middleware and locale selection, API versioning by media type, response-format and compression selection, CDNs, proxies and edge functions. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This negotiates HTTP headers; to validate or decompose a single BCP-47 language tag use a BCP-47 API.

 Punycode / IDN API — oanor API marketplace

Punycode / IDN API

Convert internationalized domain names (IDNs) between their human-readable Unicode form and the ASCII Punycode form (xn--…) that DNS actually uses. Encode a Unicode domain like münchen.de or 例え.jp (or even an emoji label like ☕.example) to ASCII, decode an xn-- domain back to Unicode, and convert a whole URL's host in either direction. Handles accents, non-Latin scripts and emoji. Useful for IDN domain handling, email and URL validation, DNS tooling, and spotting homograph / look-alike domains. Pure local IDNA conversion — no key, no third-party service, instant. Live. 4 endpoints. Distinct from Public-Suffix-List domain parsing and from generic text encoders.

 Text Segmentation API — oanor API marketplace

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.
