Flathub API

healthy 3,403 Subscribers

The Linux desktop-app store — Flathub (Flatpak) — as an API. Look up any app by its reverse-DNS id for its name, summary and description, developer, license, categories, homepage / bug-tracker / donation links, latest version and release date, screenshot count and total install count; search the whole store by keyword; and read an app's install statistics, including last-month and last-7-day installs and the top countries. Every app comes with the exact `flatpak install` command. Covers the Linux desktop from Firefox, Blender, GIMP, OBS Studio and Inkscape to VLC, Krita and LibreOffice. Live from the official flathub.org API. Ideal for app catalogs and dashboards, software-center integrations, Linux developer tooling and install-analytics. Open data from Flathub.

AUR API

The Arch User Repository (AUR) as an API. Look up any AUR package for its version, description, upstream URL, maintainer and submitter, community votes and popularity score, license, out-of-date flag, keywords and full dependency lists (depends, make-depends, opt-depends), plus its source snapshot and ready-to-run git-clone command; search the whole AUR by name, description, maintainer, dependencies or keywords (results sorted by popularity); and list every package maintained by a given user. Covers the 90,000+ community-maintained packages of Arch Linux, from yay, paru and visual-studio-code-bin to google-chrome and spotify. Live from the official AUR RPC. Ideal for Arch/AUR helpers and dashboards, package and dependency tooling, and Linux developer portals. Open data from the Arch User Repository.

App Store API

Search and look up apps on the Apple App Store as an API. Pass a search term and get matching iOS apps with their developer, average star rating and rating count, price, category and icon; or look up a single app by its App Store id (or bundle id) for the full record — description, current version, release and update dates, content rating, minimum iOS version, app size, supported languages, screenshots and the store link. Ratings and price are returned per country (default US). Live from the public iTunes Search API. Ideal for app-store optimisation (ASO), competitor and market research, app directories, review dashboards and mobile-developer tools. Public Apple data.

Sitemap API

Fetch and parse an XML sitemap (the sitemaps.org protocol). Pass a sitemap URL and the parse endpoint fetches it — following redirects and transparently gunzipping .gz sitemaps — and returns its type: a urlset with every URL and its lastmod, changefreq and priority, or a sitemapindex listing the child sitemaps, with offset/limit paging for large files. The urls endpoint goes further: when the sitemap is an index it fetches the child sitemaps too and flattens every page URL into a single list, with a configurable cap on URLs and child sitemaps and a truncated flag so you stay in control. The request is made server-side and private or internal targets are refused (SSRF-guarded). Built for SEO audits, building crawl queues and content inventories, change monitoring and migration checks. A sitemap fetcher and parser — distinct from generic XML-to-JSON conversion (xml), the robots.txt evaluator (robots) and the on-page SEO audit (seo). No upstream key, no cache.

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.
