Hex API

healthy 3,043 Subscribers

The Elixir and Erlang package ecosystem — Hex (hex.pm) — as an API. Look up any Hex package for its description, licenses, latest version, GitHub / docs / changelog links, owners and download counts (all-time and recent); read a package's complete release history with publication dates; get a single release's dependency list, Elixir version constraint and build tools; and search the entire Hex registry by keyword. Covers the Elixir/Erlang (BEAM) ecosystem from Phoenix, Ecto and Plug to Jason, Absinthe and Nerves. Live from the official hex.pm API. Ideal for package dashboards, dependency and supply-chain tooling, Elixir developer portals and BEAM ecosystem analytics. Open data from Hex.

Number Base Converter API

Convert integers between any numeral systems with exact big-integer math. Pass a number and a from/to base (radix 2 to 36, arbitrarily large, signed) and the convert endpoint returns the result and the decimal value; common 0x, 0b and 0o prefixes are accepted when they match the base, and whitespace or underscores in the input are ignored. The bases endpoint shows a single number across binary, octal, decimal, hexadecimal, base32 and base36 at once, together with its bit length, byte length and sign. Everything is computed locally with BigInt, so values of any size are exact and deterministic. Ideal for low-level and embedded debugging, networking and bit-twiddling work, teaching number systems, and anywhere you juggle hex, binary and decimal. A numeral-base converter — distinct from the text-encoding toolkit (encoding: base64/base32/hex of bytes), the Elixir/Erlang Hex package registry (hex) and number-to-words (numberwords). No upstream key, no cache.

Encoding API

A fast, fully-local encoding toolkit: encode and decode text between base64, base64url, base32 (RFC 4648), hex, URL percent-encoding, HTML entities, binary and ASCII85 — plus JWT inspection (decode header and payload without verifying the signature). Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for developer tools, webhooks, data pipelines, debugging and integrations.

Color API

A complete colour toolkit — convert between hex, RGB, HSL, HSV and CMYK with relative luminance, generate harmonious palettes (complementary, triadic, tetradic, analogous, monochromatic, shades), and compute WCAG contrast ratios with AA/AAA pass-fail for accessibility. Server-side, instant, no third-party services.

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.
