HttpResource gives you a Net::HTTP transport with a typed error hierarchy (NotFoundError, ValidationError, AuthError, ServerError, TimeoutError…), Rails-style bang/non-bang resources, pluggable auth strategies (Basic/Bearer/Header), per-call timeouts, and escape-safe URL building so untrusted path segments can never escape the protocol. Bring a base_url and an auth strategy; build clients and resources on top. Zero runtime dependencies (stdlib only).
