Speech-to-text (OpenAI

OpenAI's own transcription wire: POST multipart/form-data with a `file` part and get the transcript back. Point any Whisper-shaped SDK at this gateway and pay per call with USDC, no account and no API key. Same model and same four-minute cap as /api/transcribe, which takes a URL instead of an upload; /v1/pro/audio/transcriptions takes it to ten minutes.

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/v1/audio/transcriptions", { method: "POST" });
console.log(await res.json());
