X402-Seller — Ocean Tides
U.S. coastal tide data from NOAA — when's the next high or low tide, or what's the water level right now: high/low tide predictions for the next 48 hours (product=predictions, default), or the latest observed water level (product=water_level). Identify the location by NOAA CO-OPS station ID, or just pass lat+lng and the nearest station is used automatically (distanceKm in the response says how far it is). Heights in feet above MLLW datum, times in GMT.
