## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## App Store Critical Reviews (1-3★) Delta Monitor (Save 90%)

> 🛑 **Stop re-downloading thousands of old reviews every day just to spot a new bug.** Standard scrapers dump entire historical review feeds, creating duplicate ticket noise and high monthly bills.\
> ⚡ **The Smart Delta Solution:** **App Stores Critical Reviews Delta Monitor** queries official JSON feeds directly without browser virtualization (running in 1–2s), remembers previous review IDs, and alerts engineering teams **ONLY** on brand-new 1, 2, or 3-star reviews for instant triage — **saving 90% on compute and webhook processing.**

***

### ⚡ Why Use This Actor?

- **Zero-Browser, 100% Reliability:** Directly consumes official iTunes RSS feeds. No Puppeteer, no CAPTCHA, no IP bans. Completes in **1 to 2 seconds**.
- **Smart Delta Memory:** Deduplicates automatically using persistent Key-Value storage. Never alerts twice on the same review.
- **Pay-Per-Event (PPE):** Runs that yield zero new negative reviews cost $0 in event charges.
- **Instant DevOps & Support Integration:** Plug directly into Slack, PagerDuty, Discord, or Zendesk webhooks for critical bug discovery.

# 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 = {
    "appId": "284882215",
    "country": "us",
    "maxRating": 3,
    "maxReviews": 10,
    "resetBaseline": false
};

// Run the Actor and wait for it to finish
const run = await client.actor("titan_coder/app-stores-critical-reviews-delta").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.

    "country": "us",
    "maxRating": 3,
    "maxReviews": 10,
    "resetBaseline": False,
}

# Run the Actor and wait for it to finish
run = client.actor("titan_coder/app-stores-critical-reviews-delta").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "appId": "284882215",
  "country": "us",
  "maxRating": 3,
  "maxReviews": 10,

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,titan_coder/app-stores-critical-reviews-delta"
        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
