Steps
Obtain a Windy Point Forecast API key by registering/purchasing access through the Windy API portal.
Send a POST request to https://api.windy.com/api/point-forecast/v2 with a JSON body containing lat, lon, model, and the desired parameters/levels array, plus your API key.
Choose a forecast model appropriate for marine use (e.g., gfsWave for wave data), since different models expose different parameter sets.
Parse the returned time-series arrays (one array per requested parameter, aligned by timestamp index).
Re-request as needed for updated forecasts; historical/past forecasts are not retrievable through this API.
Known gotchas
The ECMWF model is explicitly excluded from Point Forecast due to licensing, even though it appears elsewhere on Windy's site - don't assume model parity with the Windy app.
Only forward-looking forecast data is available; there is no historical/past-forecast retrieval endpoint.
Available parameters/levels differ by model - requesting a parameter unsupported by the selected model will fail or return nothing.
