## 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 Scraper

Extract station metadata and live observations from the **NOAA Tides & Currents** service — water levels, predictions, currents, weather, and ~3,400 stations across US coastal waters, the Great Lakes, and territories.

### What this Actor does

This scraper wraps two NOAA endpoints:

- **Stations metadata API** (`mdapi.tidesandcurrents.noaa.gov/webapi/stations.json`) — discover stations by type (`tidepredictions`, `waterlevels`, `currentpredictions`, `historicwaterlevels`) and filter by state.
- **Datagetter observations API** (`api.tidesandcurrents.noaa.gov/api/prod/datagetter`) — pull live or recent readings (water level, predictions, currents, wind, air temperature, pressure) for any station ID.

No API key, no auth, no proxies.

### Fields returned

**Stations mode**

| Field | Description |
|-------|-------------|
| stationId | NOAA station ID |
| name | Station name |
| state | Two-letter state/territory |
| latitude / longitude | Coordinates |
| type | Station type |
| timezone | Local timezone |
| reference_id | Reference station ID |
| portscode | PORTS code if applicable |

**Observations mode** — adds `timestamp`, `value`, `sigma`, `flags`, `type` (H/L for tide hi/lo), and `quality`.

### How to use

1. **List stations in California:** set `stateFilter=CA`, leave other fields default. Returns all tide prediction stations in CA.
2. **Get live water level at The Battery, NY:** set `mode=observations`, `stationIds=["8518750"]`, `product=water_level`, `date=latest`.
3. **Get today's high/low tide predictions for San Francisco:** set `mode=observations`, `stationIds=["9414290"]`, `product=predictions`, `date=today`.

### Pricing

$0.003 per result. You pay only for output records. Apify compute also applies.

### Who uses this

Coastal engineers, marine logistics, insurance claims teams (flood verification), real estate due diligence, fishing & charter operators, oceanographic researchers.

### Output formats

JSON, CSV, Excel, HTML — plus an LLM-ready Markdown export for RAG pipelines.

### Legal

NOAA tides data is in the **public domain**. This actor only retrieves publicly available data. Respect NOAA's terms of use and rate limits. See [Tides & Currents — Web Services](https://tidesandcurrents.noaa.gov/web_services_info.html).

# Actor input Schema

## `mode` (type: `string`):

'stations' = list station metadata; 'observations' = fetch live readings for specific station IDs.
## `stationType` (type: `string`):

Station type for stations mode. Common values: 'tidepredictions', 'waterlevels', 'currentpredictions', 'historicwaterlevels'.
## `stateFilter` (type: `string`):

Two-letter US state/territory code (e.g. 'CA', 'FL', 'NY'). Empty = no filter.
## `stationIds` (type: `array`):

Station IDs to fetch observations for (e.g. ['8454000','9447130']). Required for 'observations' mode.
## `product` (type: `string`):

Datagetter product (e.g. 'water_level', 'predictions', 'currents', 'air_temperature', 'wind').
## `date` (type: `string`):

Date param: 'latest', 'today', 'recent', or YYYYMMDD range via begin_date/end_date not supported here; use 'today'.
## `datum` (type: `string`):

Vertical datum (MLLW, MSL, NAVD, STND).
## `units` (type: `string`):

'english' or 'metric'.
## `maxResults` (type: `integer`):

Maximum records to return. 0 = unlimited.
