Takes a recording of up to 30 minutes and creates listening-comprehension exercises like those in language exams: multiple-choice questions with four options and true/false statements, at the chosen CEFR level, in the learner's or the recording's language. Every question comes with the correct answer and the exact passage (quote and timestamp) where the answer is heard, so learners can replay it.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://medien.halowerk.com/v1/listening-quiz", { method: "POST" });
console.log(await res.json());
