Steps
Call https://api.tidesandcurrents.noaa.gov/mdapi/prod/webapi/stations/{id}/datums.json to get the valid tidal datums and their relationships (MLLW, MHHW, MSL, etc.) for the station.
Call .../stations/{id}/sensors.json to confirm which sensors (and their status) are installed.
Call .../stations/{id}/bins.json for current meter stations to get valid bin numbers and depths.
Call .../stations/{id}/harcon.json for harmonic constituents if building custom tide/current predictions.
Use the expand parameter (e.g., expand=details,sensors,datums) to fetch several of these in a single station request.
Known gotchas
Not every resource applies to every station type (e.g., bins/deployments only apply to current meter stations, tidepredoffsets only to prediction stations) — check the station's type before requesting an incompatible resource.
Datum epochs can be superseded; the supersededdatums resource exists separately from the current datums resource — make sure you're reading the currently accepted epoch.
