## 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/docs.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.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/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

## Wikidata — Structured Knowledge & Entity Search to JSON

**Search millions of Wikidata entities — as clean JSON.** Pass names of people, places, organizations or concepts and get back a tidy row per entity: label, description, aliases, statements (properties and values), Wikipedia link and Wikidata URL. Powered by the public MediaWiki / Wikidata API — no API key.

The easy way to pull structured facts into knowledge graphs, apps and AI pipelines.

### Who uses this

- 🤖 **AI / LLM & knowledge-graph builders** — ground models in structured facts.
- 🔎 **Researchers & data teams** — build entity datasets across domains.
- 🌐 **Content & search tools** — enrich pages with facts and links.
- 🧩 **Data enrichment** — resolve names to canonical IDs (QIDs).
- 🧑‍💻 **Developers** — a clean Wikidata endpoint by name.

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

| Field | Description |
|---|---|
| `id` | Wikidata QID |
| `label` | Entity label |
| `description` | Short description |
| `aliases` + `aliasCount` | Alternative names |
| `statements` | Properties and their values |
| `propertyCount` | Number of properties |
| `wikipediaUrl` + `wikipediaTitle` | Linked Wikipedia article |
| `wikidataUrl` | Wikidata entity page |
| `sitelinkCount` | Linked wiki sites |
| `query`, `scrapedAt` | Provenance |

### Example

**Input**
```json
{ "queries": ["Douglas Adams", "Mount Everest"], "language": "en", "maxResultsPerQuery": 10 }
````

**Output (one item)**

```json
{
  "id": "Q42",
  "label": "Douglas Adams",
  "description": "English writer and humorist (1952–2001)",
  "aliases": ["Douglas Noël Adams", "DNA"], "aliasCount": 2,
  "propertyCount": 120,
  "wikipediaUrl": "https://en.wikipedia.org/wiki/Douglas_Adams",
  "wikidataUrl": "https://www.wikidata.org/wiki/Q42"
}
```

### Why this actor

- ✅ **Structured facts** — properties and values, not just text.
- 🌐 **Any language** — labels, descriptions and Wikipedia links localized.
- 🔗 **Canonical IDs** — resolve names to Wikidata QIDs.
- 📚 **Wikipedia links** — jump from entity to article.
- ⚡ **Fast & affordable** — pay only per entity returned. No API key.

### Input options

- `queries` *(required)* — entity names to look up.
- `language` — language code for labels/descriptions (default `en`).
- `maxResultsPerQuery` — cap entities per query.

### FAQ

**What are statements?** Property→value facts (e.g. "instance of → human"), returned as a structured list.

**Do I get the Wikidata QID?** Yes — `id` is the canonical QID (e.g. `Q42`).

**Which languages?** Any Wikidata language — set `language`.

**How fresh is the data?** Live from the MediaWiki/Wikidata 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-entity — you're only charged for entities actually returned.

***

*Tip: pair this with the Wikipedia actor — resolve a name to a QID here, then pull the article summary there.*

# Actor input Schema

## `queries` (type: `array`):

Entities to look up (people, places, organizations, concepts). One search per query.

## `language` (type: `string`):

Language code for labels, descriptions, aliases and Wikipedia link (e.g. en, fr, de, es).

## `maxResultsPerQuery` (type: `integer`):

Cap the number of entities returned per query.

## `healthCheckMode` (type: `boolean`):

Internal monitoring: run a canary search and FAIL if broken (no billing).

## Actor input object example

```json
{
  "queries": [
    "Marie Curie",
    "Tesla Inc",
    "Mount Everest"
  ],
  "language": "en",
  "maxResultsPerQuery": 10,
  "healthCheckMode": false
}
```

# Actor output Schema

## `entities` (type: `string`):

All matched entities (label, description, aliases, statements, Wikipedia link).

# 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 = {
    "queries": [
        "Douglas Adams"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("omao/wikidata").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);
});
