## 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.

# README

## IMSLP Sheet Music Scraper

Scrape free public domain sheet music from [IMSLP](https://imslp.org) (International Music Score Library Project / Petrucci Music Library) — the largest collection of free sheet music in the world with 200,000+ works.

### What it does

Search by composer name or work title to get structured metadata for classical music scores:

- **Title & Composer** — Parsed from IMSLP's canonical format
- **Opus/Catalogue Numbers** — Op., WoO, BWV, K., RV, D., HWV, Hob., etc.
- **Key** — Musical key (e.g. "C-sharp minor")
- **Instrumentation** — e.g. "piano", "orchestra", "string quartet"
- **Genre/Style** — Classical, Romantic, Baroque, etc.
- **Year of Composition**
- **Movements** — Parsed movement list
- **Edition Count** — Number of available PDF editions
- **PDF URLs** — Direct links to downloadable score PDFs
- **Source URL** — Link back to the IMSLP work page

### Input

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `searchQueries` | string[] | `["Beethoven"]` | Composer names or work titles |
| `maxListings` | integer | 50 | Max works to return (1-1000) |
| `scrapeDetails` | boolean | false | Visit work pages for full metadata |
| `proxyConfiguration` | object | — | Optional proxy settings |

#### Search modes

- **Composer search** (e.g. "Beethoven", "Bach") — Lists all works in that composer's category
- **Work search** (e.g. "Moonlight Sonata", "Clair de Lune") — Searches across all works

#### Detail scraping

With `scrapeDetails: false` (default), you get title, composer, opus number, and source URL — fast and lightweight.

With `scrapeDetails: true`, each work page is visited to extract key, instrumentation, genre, year, movements, PDF links, and edition counts. This is slower but provides rich metadata.

### Output example

```json
{
  "title": "Piano Sonata No.14, Op.27 No.2",
  "composer": "Beethoven, Ludwig van",
  "opusNumber": "Op.27 No.2",
  "key": "C-sharp minor",
  "instrumentation": "piano",
  "genre": "Classical",
  "year": "1802",
  "movements": ["Adagio sostenuto", "Allegretto - Trio", "Presto agitato"],
  "editions": 85,
  "pdfUrls": ["https://imslp.org/images/..."],
  "sourceUrl": "https://imslp.org/wiki/Piano_Sonata_No.14,_Op.27_No.2_(Beethoven,_Ludwig_van)",
  "scrapedAt": "2026-04-26T12:00:00.000Z"
}
````

### Use cases

- **Music researchers** — Catalog and analyze classical music metadata at scale
- **Music educators** — Find free sheet music for teaching
- **App developers** — Build music discovery tools with structured data
- **Digital humanities** — Analyze composers, genres, and time periods
- **Performers** — Discover available editions of specific works

### Technical notes

- Uses IMSLP's MediaWiki API for fast, reliable search and category listing
- Individual work pages are scraped with Cheerio for full metadata
- Respects rate limits with built-in delays when scraping details
- All sheet music on IMSLP is public domain or Creative Commons licensed

# Actor input Schema

## `searchQueries` (type: `array`):

Composer names or work titles to search for. E.g. 'Beethoven', 'Moonlight Sonata', 'Bach, Johann Sebastian'.

## `maxListings` (type: `integer`):

Maximum number of works to return across all queries.

## `scrapeDetails` (type: `boolean`):

Visit each work page for full metadata (key, instrumentation, movements, PDF links). Slower but more data.

## `proxyConfiguration` (type: `object`):

Optional proxy to use.

## Actor input object example

```json
{
  "searchQueries": [
    "Beethoven"
  ],
  "maxListings": 50,
  "scrapeDetails": false
}
```

# 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": [
        "Beethoven"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("lulzasaur/imslp-scraper").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) => {
