## 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

## Global Air Quality Monitor

Real-time aggregation of 4 international air quality APIs with composite air quality scoring (0-100) and pollution risk assessment.

### Purpose

This Actor analyzes air quality and pollution risk for any country by combining data from:
- **NOAA National Weather Service** - Real-time air quality alerts (US only)
- **Our World in Data** - Historical pollution-related death rates
- **World Bank** - PM2.5 exposure, CO2 emissions, methane emissions
- **GDELT Project** - Recent air quality and pollution news sentiment

Produces:
1. **Air Quality Score (0-100)** - Higher is better (lower pollution)
2. **Pollution Risk Score (0-100)** - Higher is worse (more risk)

### Input

#### Required
- **countryCode** (string) — Two-letter ISO country code (e.g., `US`, `IN`, `KR`)

#### Optional
- **state** (string) — US state code only (e.g., `CA`, `NY`). Enables NOAA air quality alerts for that state. Ignored for non-US countries.

### Output

```json

  "query": {
    "countryCode": "US",
    "state": "CA"
  },

### Examples

#### Basic Usage (Global)

```json
{
  "countryCode": "IN"
}
```

#### US with State-Level Alerts

```json
{
  "countryCode": "US",
  "state": "CA"
}
```

#### Another Country

```json
{
  "countryCode": "GB"
}
```

### Data Coverage

| Indicator | Coverage | Countries |
|-----------|----------|-----------|
| NOAA Alerts | US only | United States (all 50 states) |
| Pollution Death Rate | 180+ countries | Our World in Data participants |
| PM2.5 Exposure | World Bank members | 180+ countries |
| CO2 Emissions | World Bank members | 180+ countries |
| Methane Emissions | World Bank members | 180+ countries |
| News Sentiment | Global | All countries with news coverage |

### Scoring Methodology

#### Air Quality Score (0-100, higher is better)

- **35%** PM2.5 average exposure (target: <15 μg/m³)
- **30%** Pollution-related death rate
- **20%** CO2 emissions per capita (target: <5 tons)
- **15%** Methane emissions

#### Pollution Risk Score (0-100, higher is worse)

- PM2.5 > 35 = high risk
- PM2.5 > 55 = very high risk
- CO2 per capita > 10 tons = high
- Death rate > 20 = concerning

### Pricing

- **$0.12 per query** (Pay-per-Event model)
- Billed only when analysis completes successfully
- No charge if all upstream APIs fail
