  description: >-
    Every Sinay API endpoint requires authentication with an API key. The key is
    sent in a request header named API_KEY (for example `API_KEY: your-api-key`).
    The same scheme applies across all Sinay products (Ports & Vessels, Metocean,
    CO2 Emission, ETA, Port Congestion). Create a free key on the Sinay Developers
    Platform at https://developers.sinay.ai/. Confirmed from the live per-product
    Swagger securitySchemes (apiKey / header / API_KEY) on 2026-07-12.
