Get a Predict Sea API key

A free beta, with no service-level agreement. Self-serve keys allow 30 requests a minute and 1,000 weight units a day (UTC); ask if you need more.

Use the key from your server only, never in a web page or an app. Forecasts are guidance only, not for navigation.

We email you a link; it opens a page with one button that creates your key. Once you confirm, we store your address, your name and what you will build: see how your details are used.

One key per person or organisation. Already have a key? Manage it.
