## 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

## Wikipedia — Article Summaries & Search to JSON

**Get clean Wikipedia article summaries by title or search — as JSON, in any language.** Pass article titles or search queries and get back a tidy row per article: title, short description, extract, thumbnail, coordinates and URL. Powered by the official Wikipedia API — no API key, no anti-bot.

The easy way to pull encyclopedic knowledge into apps, datasets and AI pipelines.

### Who uses this

- 🤖 **AI / LLM & RAG pipelines** — feed clean article extracts to your models.
- 🔎 **Researchers & analysts** — build knowledge datasets on any topic.
- ✍️ **Content & education tools** — enrich pages with summaries and thumbnails.
- 🌍 **Localization** — pull the same topic in multiple languages.
- 🧑‍💻 **Developers** — a clean Wikipedia endpoint by title or search.

### What you get — one clean row per article

| Field | Description |
|---|---|
| `title` | Article title |
| `description` | Short description |
| `extract` | Clean summary text |
| `thumbnail` + `image` | Images |
| `lang` | Language |
| `pageId` | Wikipedia page ID |
| `latitude` + `longitude` | Coordinates (for places) |
| `wikibaseItem` | Linked Wikidata ID |
| `url`, `timestamp`, `scrapedAt` | Link & provenance |

### Example

**Input**

```json
{ "titles": ["Alan Turing", "Python (programming language)"], "searchQueries": ["machine learning"], "language": "en", "resultsPerQuery": 10 }
```

**Output (one item)**

```json
{
  "title": "Alan Turing",
  "description": "English mathematician and computer scientist (1912–1954)",
  "extract": "Alan Mathison Turing was an English mathematician, computer scientist, logician...",
  "lang": "en", "pageId": 1208,
  "wikibaseItem": "Q7251",
  "url": "https://en.wikipedia.org/wiki/Alan_Turing"
}
```

### Why this actor

- ✅ **Official source** — the Wikipedia API, always current.
- 🌐 **Any language** — set the language code (en, fr, de, es…).
- 🔎 **Title *or* search** — exact titles or keyword queries.
- 🧹 **Clean extracts** — plain-text summaries, ready for LLM/RAG.
- ⚡ **Fast & affordable** — pay only per article returned. No key, no anti-bot.

### Input options

- `titles` — exact article titles.
- `searchQueries` — keyword searches.
- `language` — Wikipedia language code (default `en`).
- `resultsPerQuery` — cap results per search query.

### FAQ

**Title or search?** Both — pass `titles` for exact articles and `searchQueries` for keyword search.

**Which languages?** Any Wikipedia language — set `language` (e.g. `en`, `fr`, `de`, `es`, `ja`).

**Is the summary clean text?** Yes — `extract` is plain text, ideal for LLM/RAG ingestion.

**How fresh is the data?** Live from the Wikipedia API on every run.

**Can I export to CSV/Excel/Google Sheets?** Yes — the dataset exports to JSON, CSV, Excel and HTML, or pull it via the API.

**What does it cost?** Pay-per-article — you're only charged for articles actually returned.

*Tip: pair this with the Wikidata actor to enrich articles with structured facts via the `wikibaseItem` ID.*

# 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 = {
    "searchQueries": [
        "machine learning"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("omao/wikipedia").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 = { "searchQueries": ["machine learning"] }

# Run the Actor and wait for it to finish
run = client.actor("omao/wikipedia").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 '{
  "searchQueries": [
    "machine learning"
  ]
}' |
apify call omao/wikipedia --silent --output-dataset

```

## MCP server setup

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

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).
