Methods (6)

  • searchStations

    read

    Find stations by catalog (type), state, bbox, near-point, or name substring.

    type: tidepredictions/currentpredictions/historicwl/watertemp/met/harcon.

  • getStation

    read

    Single station detail. expand: datums | sensors | harcon | products.

    Use expand:["datums"] before requesting an unusual datum to confirm support.

  • getWaterLevels

    read

    Observed water levels (preliminary real-time or verified historic). 31-day cap.

    datum default MLLW. Pass productMode: verified for QC-passed historic data.

  • getTidePredictions

    read

    Astronomical tide predictions — hi/lo (default) or 6-min/hourly series.

    interval=hilo or h: 365-day cap. interval=1|5|6|10|15|30|60: 31-day cap.

  • getMeteorological

    read

    Coastal meteorology — wind, air_temperature, water_temperature, air_pressure.

    31-day request cap on all 4 products. Wind returns value + direction + gust.

  • getServiceInfo

    read

    Live station counts by catalog, supported products, datum/unit/timezone enums, caps.
