Free public LibreTranslate instances have largely shut down. You must supply your own: self-hosted, libretranslate.com (paid), or a community instance. The pack accepts an endpoint URL + optional API key.

TypeScript 
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.call("translate", {"text":"example","target":"example"});
ask_pipeworx 
// Or ask in plain English:
const answer = await px.ask("open-source ml translation");
