SDKs

Each SDK signs in with your recovery phrase or an API key, creates addresses that receive mail, opens what arrives, sends with attachments, and listens for events. The keys are derived from the phrase on your machine; the phrase is never sent.

Language	Package	Install
TypeScript	mailcycle-sdk on npm	npm install mailcycle-sdk	Available
Python	mailcycle on PyPI	pip install mailcycle	Available
Go	mailcycle.email/go	go get mailcycle.email/go	Available
Rust	mailcycle on crates.io	cargo add mailcycle	Available
Swift	mailcycle.email/swift/mailcycle.git	.package(url: "https://mailcycle.email/swift/mailcycle.git", from: "0.1.0")	Available
PHP	mailcycle/mailcycle on Mailcycle’s Composer repository	composer require mailcycle/mailcycle	Available
Java	email.mailcycle:mailcycle on Maven Central	implementation("email.mailcycle:mailcycle:0.3.0")	Available
.NET	Mailcycle on NuGet	dotnet add package Mailcycle	Available
Ruby	mailcycle on RubyGems	gem install mailcycle	Available

The Swift line goes in the dependencies of your Package.swift. For PHP, add the repository first with composer config repositories.mailcycle composer https://mailcycle.email/php. The Java line is for Gradle; with Maven, the guide has the <dependency> block.

All of them implement the same encryption format and are checked against the same test vectors, so mail sealed by one opens in any other and in the apps.

The encryption format is published, so you can write a client now rather than wait. Plain HTTP calls also work without any SDK for everything except opening mail and creating addresses that receive it: see Authentication and Email addresses.
