## Pricing

from $0.04 / 1,000 audio download successes

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## 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

## Titan YouTube Audio Downloader (MP3)

Download **audio only** from YouTube videos as **MP3** (current Gateway supports MP3 only — no M4A/FLAC).

> Powered by [Titan Network](https://apify.com/Titan_Network) via the **Titan Apify Gateway** · Not affiliated with YouTube or Google.

***

### 🌟 Key Features

- This Actor is the **Gateway version** of the old `youtube-audio` actor: it is fixed to `outputType=media` + `format=mp3` (quality always 720) and delivers `<video_id>.mp3` (kind=audio) plus the attached `<video_id>.info.json` (kind=metadata) in `downloadFiles`.
- **Shorts & Standard Videos**: Fully supports standard YouTube videos, YouTube Shorts, and `youtu.be` short links.
- **Zero Memory Overhead (Ultra-Lightweight)**: Runs smoothly on Apify's minimal **128MB RAM** tier.
- **Direct High-Speed Delivery**: Pre-signed download links (retained ~24h) — no slow double-transfers.
- **Custom Cloud Storage Integration**: Pipe outputs into your Amazon S3, Google Cloud Storage, or DigitalOcean Spaces bucket. Azure is not supported.
- **Real-time Progress**: Live status via Apify Console (fetching metadata / downloading / processing / uploading).
- **Bounded Concurrency + Configurable Timeout**: Default 20 concurrent worker units (1-50) and a configurable per-task timeout.

#### Example Input JSON

```json
{
  "startUrls": ["https://www.youtube.com/watch?v=dQw4w9WgXcQ", "9bZkp7q19f0"],
  "maxConcurrency": 5
}
```

### 💰 Pricing & Monetization (Pay-Per-Event)

- Billing event: **`audio-download-success`** — charged only when the Gateway returns `completed`, the requested output files exist, and the Dataset row was written successfully.
- Zero cost on failures, timeouts, cancellations, or missing output files.

# Actor input Schema

## `startUrls` (type: `array`):

List of YouTube video URLs (watch links, Shorts, youtu.be) or plain 11-character video IDs. One item per line. Duplicate video IDs are processed once. This Actor downloads MP3 audio (with attached .info.json metadata).

## `storageType` (type: `string`):

Destination where downloaded files will be stored: apify (Titan platform storage, pre-signed links valid ~24h; files are NOT copied to the Apify Key-Value Store), aws (Amazon S3), gcp (Google Cloud Storage), digitalocean (DigitalOcean Spaces). Azure is not supported.

## `s3Bucket` (type: `string`):

Bucket or container name if using custom cloud storage (required for aws/gcp/digitalocean).

## `s3Region` (type: `string`):

Region of your storage bucket (e.g. us-east-1, auto, nyc3). Required for DigitalOcean Spaces.

## `s3AccessKeyId` (type: `string`):

Access Key ID for your cloud storage provider (required for aws/gcp/digitalocean).

## `s3SecretAccessKey` (type: `string`):

Secret Access Key for your cloud storage provider (required for aws/gcp/digitalocean).

## `maxWaitSec` (type: `integer`):

Maximum seconds to wait for each task's SSE completion before cancelling it. Default 7200 (2 hours).

## `maxConcurrency` (type: `integer`):

echo '{
  "startUrls": [
    "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
  ]
}' |
apify call titan_network/titan-youtube-audio --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,titan_network/titan-youtube-audio"

```

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).
