Carnival Corporation
Carnival Corporation & plc is the world's largest cruise company operating eight cruise line brands (Carnival Cruise Line, Princess Cruises, Holland America Line, Seabourn, Cunard, P&O Cruises, Costa Cruises, AIDA Cruises), plus the White Pass and Yukon Route. Carnival operates the OceanMedallion wearable IoT technology and mobile experience platform, the Carnival HUB app, the Princess MedallionClass app, and a portfolio of guest-facing digital experiences across its fleet of over 90 ships.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Carnival Corporation the way a machine reads it — 30 machine-readable artifacts across 8 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Carnival Corporation scores 9.2/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

APIs 8
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
