Input

{
  "state": "NY",
  "stationId": "",
  "product": "waterLevel",
  "maxResults": 25
}

Field	Type	Description
`state`	string	Two-letter US state code to survey all tide stations in. Ignored if `stationId` is set.
`stationId`	string (optional)	A specific NOAA CO-OPS station ID to check instead of a whole state, e.g. `"8518750"` (The Battery, NY).
`product`	string	`"waterLevel"`, `"waterTemperature"`, `"airTemperature"`, or `"airPressure"`. Default `"waterLevel"`.
`maxResults`	number	Max stations to return when surveying a state. Default `25`, max `100`.

Either state or stationId is required.

Output

One record per station:

{
  "stationId": "8518750",
  "stationName": "The Battery",
  "latitude": 40.7006,
  "longitude": -74.0142,
  "product": "water_level",
  "value": 5.102,
  "time": "2026-08-15 21:48"
}

Water level is in feet relative to the station's Mean Lower Low Water (MLLW) datum, the standard NOAA tidal reference. Stations with no current reading for the selected type are silently skipped.

A search with no matching stations returns no items but is still billed once for the search.

How it works

Direct calls to the official NOAA CO-OPS Tides & Currents API — no proxy, no key, no scraping. Public U.S. government data, updated every 6 minutes per station.

Pricing note

Billed per search, not per station returned — one charge whether the search returns 0 stations or 100.

NOAA Sea Level Rise Screener - Site Inundation Threshold

malonestar/noaa-slr-inundation-threshold-screener

Batch coordinates to the NOAA sea level rise increment at which each site first floods (0-10 ft above MHHW), with confidence class, inundated vs low-lying split, levee-exclusion flag and nearest high-tide-flooding thresholds. Out-of-coverage is reported explicitly, never as a false clear. MCP-ready.
