## Pricing

from $2.00 / 1,000 nws active weather alerts scraper api evidence items

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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/docs.md):

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

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## NWS Active Weather Alerts Scraper API

Search the official National Weather Service active-alert GeoJSON endpoint by state/area, point, NWS zone, or region. Filter warning evidence by event, urgency, severity, certainty, status, message type, and RFC3339 overlap window.

### Fast default

```json
{"area":"CA","maxResults":3}
````

This preserves NWS order and returns up to three active California alerts, or one explicit `NO_MATCH` record. At **$0.0001/start + $0.002/item**, the default costs at most **$0.0061**.

Official endpoint:

```bash
curl -H 'User-Agent: your-app/1.0 (you@example.com)' -H 'Accept: application/geo+json' 'https://api.weather.gov/alerts/active?area=CA'
```

FOUND rows normalize alert ID, event, headline, description, instruction, area and affected zones, timestamps, severity/certainty/urgency, sender, response type, geocode, geometry, source URL, retrieval time, and NWS update metadata. Invalid input, no match, and exhausted source retries are distinct explicit outcomes.

### Important safety limits

Alerts are dynamic NWS-issued public warning evidence—not a complete historical archive, forecast, guaranteed delivery service, localized safety determination, or substitute for emergency instructions. Geometry and area descriptions may be broad; alerts may be updated, replaced, or cancelled. Always check current weather.gov/local emergency channels and follow official safety instructions.

See the full README for all fields, examples, filters, and time semantics.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "area": "CA",
    "maxResults": 3
};

// Run the Actor and wait for it to finish
const run = await client.actor("pink_comic/nws-active-weather-alerts").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {
    "area": "CA",
    "maxResults": 3,
}

# Run the Actor and wait for it to finish
run = client.actor("pink_comic/nws-active-weather-alerts").call(run_input=run_input)
