A profile of the Ruby programming language ecosystem from an API perspective: the language and its standard library HTTP surface (Net::HTTP), the rubygems.org package registry and its public v1/v2 REST API, Bundler, RBS type signatures, popular HTTP/REST client gems (Faraday, http.rb, HTTParty, Excon, Typhoeus, REST Client, HTTPClient), and the major Ruby frameworks used to build APIs (Rails API mode, Sinatra, Grape).

The HTTP client class shipped with the Ruby standard library. Provides class and instance methods for GET, POST, PUT, DELETE, HEAD, PATCH, OPTIONS, TRACE plus WebDAV methods (COPY, LOCK, MKCOL, MOVE, PROPFIND, PROPPATCH, UNLOCK), TLS, proxy support, and configurable timeouts. Backs many higher-level gems such as Faraday's default adapter.
