Multi-source
Agreement you can see
Every timestamp carries a value per source. When models agree, trust the number; when they diverge, you know the forecast is uncertain.
Marine & weather API · MCP-native
Wave, swell, wind, tide and current data assembled on demand from NOAA, ECMWF, DWD and Copernicus — returned as one schema with one value per source, so you can see where the models agree and where they diverge. For you, or your AI agent.

One schema across every endpoint. Each field returns a value per source, attributed by name — NOAA, ECMWF, DWD, Copernicus — so agreement and divergence are part of the response, not a footnote.
