title: Sinay Maritime APIs CO2 Emission Usage API
description: 'Consolidated OpenAPI description of five Sinay Developers Platform APIs - Ports and Vessels, Metocean, CO2 Emission, ETA (ETAC), and Port Congestion. Every Sinay API is served over HTTPS from the single host api.sinay.ai, with each product mounted under its own versioned base path (for example `/co2/api/v2` or `/ports-vessels/api/v1`). All endpoints require an API key passed in an `API_KEY` request header; get a free key from the Sinay Developers Platform (https://developers.sinay.ai/).
This document consolidates the individual per-product Swagger files published live at https://api.sinay.ai/<product>/api/<version>/swagger.yaml (confirmed 2026-07-12). Paths, methods, the API_KEY security scheme, and the CO2 / ETA / congestion request and response shapes below are taken directly from those live specs. Where a request or response body is only summarized here rather than fully expanded, consult the upstream per-product Swagger.'
