## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## NOAA Tides & Currents Stations Scraper

Extract metadata for **3,400+ NOAA Tides & Currents observation stations** across the United States and territories — including station ID, name, coordinates, state, station type, and timezone references. Optionally enrich each station with the **latest observed water level reading** (referenced to MLLW datum).

This Actor wraps the public NOAA Tides & Currents MDAPI and Datagetter endpoints. Data is sourced from the [NOAA Center for Operational Oceanographic Products and Services (CO-OPS)](https://tidesandcurrents.noaa.gov/) and is updated continuously as new readings come in from physical stations along U.S. coastlines, the Great Lakes, and Pacific/Caribbean territories.

### Features

- **All NOAA station types** — tide predictions, water levels, currents, current predictions
- **State filtering** — narrow to one state (e.g. `FL`, `CA`, `WA`)
- **Latest water levels** — optionally pull the most recent observed water level (feet, MLLW) per station
- **Geocoded** — every record includes latitude/longitude for mapping
- **Station page links** — direct deep-link to the official NOAA station page

### Output fields

| Field | Description |
|-------|-------------|
| `stationId` | NOAA station identifier (e.g. `8454000`) |
| `name` | Station name (e.g. `Providence`) |
| `state` | Two-letter state code |
| `type` | Station type (tide, water level, etc.) |
| `latitude` / `longitude` | Geo-coordinates |
| `referenceId` | Reference station ID for tide subordinates |
| `timeMeridian` / `timeZoneCorr` | Local time references |
| `latestWaterLevelFeet` | Latest observed water level (MLLW datum, ft) — when enabled |
| `latestWaterLevelTimeGmt` | Timestamp of the latest reading (GMT) |
| `stationPageUrl` | Link to the NOAA station home page |
| `metadataUrl` | API URL to full station metadata |

### Use cases

- **Maritime operations** — pull station inventories for port operators, dredging companies, USCG support contractors
- **Climate research** — identify coastal monitoring sites by region for sea-level rise studies
- **Tide-dependent businesses** — fishing charters, harbor pilots, coastal surveyors integrating real-time tide data
- **Insurance & risk modeling** — flood-zone underwriting using authoritative tide gauge locations

### How to use

1. Set `stationType` to the dataset you want (default `tidepredictions`).
2. Optionally filter by `stateFilter` (two-letter code).
3. Toggle `includeLatestWaterLevel` to enrich each station with its newest observation.
4. Set `maxResults` to cap the run (default 1000, max 5000).

### Pricing

Pay-per-result at **$0.003/record**. A nationwide tide-predictions pull (~3,400 records) costs around $10. Apify compute cost is minimal — most runs finish in under 2 minutes without water-level enrichment.

### FAQ

**Where does the data come from?**
The NOAA Center for Operational Oceanographic Products and Services (CO-OPS), a U.S. federal agency. Data is in the public domain.

**Is real-time water level data available?**
Yes — enable `includeLatestWaterLevel`. This adds one HTTPS call per station, so large pulls take longer.

**Are predictions included?**
This Actor returns station metadata. Tide *predictions* for specific dates are a separate NOAA endpoint; let us know if you need that variant.

### Legal

NOAA data is in the public domain under U.S. federal policy. This Actor only accesses publicly published endpoints and stores no personal data. Use complies with NOAA Acceptable Use guidelines.

# Actor input Schema

## `stationType` (type: `string`):

Type of station to list: 'tidepredictions', 'waterlevels', 'currents', 'currentpredictions'.
## `stateFilter` (type: `string`):

Two-letter state code to filter (e.g. 'CA', 'FL'). Leave blank for all states.
## `includeLatestWaterLevel` (type: `boolean`):

If enabled, fetch the latest observed water level (MLLW, ft) for each station. Adds one request per station.
## `maxResults` (type: `integer`):

Maximum number of stations to return. 0 = unlimited.

## Actor input object example

```json
{
  "stationType": "tidepredictions",
  "stateFilter": "",
  "includeLatestWaterLevel": false,
  "maxResults": 1000
