## 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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Language Detector (offline)

Detect the **language** of text in bulk — **100% offline** (franc, 400+ languages), no key, no proxy, no external calls.

### Input

```json
{ "texts": ["Hello world", "Olá mundo, tudo bem?", "Bonjour le monde"], "minLength": 10 }
```

### Output (per text)

```json
{
  "text": "Olá mundo, tudo bem?",
  "language_code": "por",
  "language": "Portuguese",
  "reliable": true,
  "candidates": [
    { "code": "por", "language": "Portuguese", "score": 1 },
    { "code": "glg", "language": "Galician", "score": 0.94 }
  ]
}
```

### Use cases

- Route content / support tickets by language
- Content moderation & i18n pipelines
- Clean and tag multilingual datasets

Returns ISO 639-3 codes with human-readable names. Very short text may return `und` (undetermined). Billed per **text detected**.

# Actor input Schema

## `texts` (type: `array`):

Text snippets to detect the language of. Example: Hello world, Olá mundo, Bonjour le monde.

## `minLength` (type: `integer`):

Minimum text length to attempt detection (shorter returns 'und'). Default 10.

## Actor input object example

```json
{
  "texts": [
    "Hello world, how are you?",
    "Olá mundo, tudo bem?",
    "Bonjour le monde"
  ],
  "minLength": 10
}
```

# 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 = {
    "texts": [
        "Hello world, how are you?",
        "Olá mundo, tudo bem?",
        "Bonjour le monde"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("bgfc97/language-detector").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 = { "texts": [
        "Hello world, how are you?",
        "Olá mundo, tudo bem?",
        "Bonjour le monde",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("bgfc97/language-detector").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():
    print(item)
