Returns the latest NDBC buoy observation including wind, gusts, wave height, swell, barometric pressure, and water temperature, with Beaufort wind force and Douglas sea-state classification.
- [Marine Conditions – Tide Predictions](https://www.zero.xyz/c/marine-conditions-tide-predictions-f4a52927/llms.txt): $0.03/call via x402. Returns upcoming high and low tide predictions for a NOAA CO-OPS tide station, including UTC and local times, heights in feet above MLLW, tidal range, and next tide.
- [Marine Conditions – Nearest NOAA/NDBC Buoys](https://www.zero.xyz/c/marine-conditions-nearest-noaa-ndbc-buoys-df5835dc/llms.txt): $0.02/call via x402. Returns the nearest active NOAA/NDBC weather buoys and stations to a given lat/lon, with distance, owner, and type information.
- [Marine Conditions – Real-Time Water Level vs. Tide Prediction](https://www.zero.xyz/c/marine-conditions-real-time-water-level-vs-tide-prediction-98e06df3/llms.txt): $0.03/call via x402. Returns the latest observed water level at a NOAA CO-OPS station compared to its tide prediction, expressing the difference (surge or blow-out) in feet.
