Speech-to-text (Pro)

Transcribe audio to text with the gpt-transcribe model - the same model as /api/transcribe with a longer cap. Provide a URL to an audio file and get back the transcript; add diarize:true for speaker labels, word timestamps and a language confidence score (the scribe-v2 model). No API key needed; pay per call via x402. Max 10 minutes of audio, 25 MB file size.

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/transcribe-pro", { method: "POST" });
console.log(await res.json());
