Text-to-speech (lite)

Convert text to speech with Kokoro-82M, ten times cheaper than /api/tts. Returns base64-encoded mp3 or pcm. The same request shape and the same ten OpenAI voice names as /api/tts, mapped to Kokoro's own voices; the voice is synthetic-sounding where the OpenAI tiers are not, which is the whole trade. Use this for high-volume narration, notifications and agent speech where the cost per call matters

Call it from code

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://agent402.tools/api/tts-lite", { method: "POST" });
console.log(await res.json());
