# MP3 download links for free LibriVox audiobooks

**Use case:** 

Searches the LibriVox collection on archive.org for the most-downloaded public-domain audiobooks and returns one row per MP3 file — download URL, chapter name, format, size, duration and checksum — with the item’s title, author and page URL alongside. Everything in the collection is public domain, so the files are free to download. $0.40 per 1,000 items, $0.10 per 1,000 file rows.

## About this Actor

This example demonstrates how to use [Internet Archive API — Search, Metadata & Files](https://apify.com/insight.solutions/internet-archive-api.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/insight.solutions/internet-archive-api.md) to learn more, explore other use cases, and run it yourself.


## 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.
This Task's input is already configured above — use it as-is rather than inventing a new one.

- **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).
