## 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

## Telegram Username Checker & Profile Extractor

A high-speed, batch-processing Apify Actor to check Telegram username availability and retrieve complete profile details (title, type, verified status, subscribers count, bio, and avatar URL) when they are taken.

***

### Features

- 🔍 **Availability Checker:** Check if any username is taken or available in real-time.
- 📊 **Account Info Extractor:** If taken, it parses and returns the display title, account type (channel, user, group, bot), verified badge status, bio description, subscriber/member counts, and avatar profile picture URL.
- 🗂️ **Database-Friendly Flat Mapping:** Automatically transforms nested validations into flat columns, making them immediately viewable, downloadable as CSV, or syncable with database tables.

***

### Input Parameters

The actor accepts the following parameters:

| Field | Type | Description |
|---|---|---|
| **usernames** | `array` | A list of Telegram usernames to check (one username per item/line, e.g. @telegram or telegram). |

***

### Output Examples

#### 1. Verification Results Dataset (CSV/JSON Flat Structure)

```json
{
  "username": "telegram",
  "available": false,
  "taken": true,
  "title": "Telegram News",
  "avatar": "https://cdn1.telesco.pe/file/Z83JGBAWubU2OQJa...",
  "verified": true,
  "type": "channel",
  "bio": "The official Telegram on Telegram. Much recursion. Very Telegram. Wow.",
  "subscribers": 10214087
}
```

#### 2. Raw JSON Payload Array

The complete raw JSON response array returned by the backend is stored in the default Key-Value Store under the key `OUTPUT`.

# 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 = {
    "usernames": [
        "telegram"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("dev00/telegram-username-checker").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 = { "usernames": ["telegram"] }

# Run the Actor and wait for it to finish
run = client.actor("dev00/telegram-username-checker").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 '{
  "usernames": [
    "telegram"
  ]
}' |
apify call dev00/telegram-username-checker --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dev00/telegram-username-checker"
        }
    }
}

```

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).
