Marine conditions API: current wave height, wave period, swell wave height, and sea surface temperature for any ocean latitude/longitude worldwide, as structured JSON from a global marine weather model. Use for shipping, boating, surf forecasting, and offshore-operations agents. Coverage is open water only — points far from any ocean may return null values. Cached 10 minutes.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
