## 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.

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



# Actor input Schema

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

search = find apps by niche; lookup = details for given app IDs; reviews = pull country reviews.
## `searchTerm` (type: `string`):

Niche to research (e.g. 'habit tracker', 'meditation'). Used in search mode.
## `country` (type: `string`):

ISO country of the source store (us, gb, ...). Leave 'us' to find US winners.
## `maxResults` (type: `integer`):

Max apps to return in search mode (max 200).
## `appIds` (type: `array`):

iTunes app IDs for lookup/reviews mode (e.g. '337472899').
## `checkLanguage` (type: `string`):

ISO language to check (de, fr, es, it). Apps NOT supporting it are flagged missingLanguage=true.
## `includeReviews` (type: `boolean`):

Also pull reviews for each app found (slower).
## `reviewCountry` (type: `string`):

Country to fetch reviews from (e.g. search US apps, read DE reviews). Defaults to checkLanguage's market.
## `reviewPages` (type: `integer`):

Pages of reviews per app (1 page ~50 reviews, max 10).
## `filterKeywords` (type: `array`):

Only keep reviews containing these words (e.g. 'translate','german','language').

# 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 = {
    "searchTerm": "habit tracker",
    "country": "us",
    "checkLanguage": "de"
};

// Run the Actor and wait for it to finish
const run = await client.actor("agency-shift/appstore-localization-gaps").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 = {
    "searchTerm": "habit tracker",
    "country": "us",
    "checkLanguage": "de",
}

# Run the Actor and wait for it to finish
run = client.actor("agency-shift/appstore-localization-gaps").call(run_input=run_input)

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