Flux Asr (Speech to Text)

Flux Asr (slug: flux-asr) transcribes spoken audio to text.

Endpoint

URL: POST /:modelSlug with modelSlug = flux-asr
Auth: Authorization: Bearer <api_key>
Content-Type: application/json
Base URL: https://aiworker.linconwaves.com

Request

Send audio as a byte array and optional prompt.

{
  "audio": [82, 73, 70, 70],
  "prompt": "Transcribe this clip"
}

Notes:

Provide audio bytes (PCM/WAV/MP3, etc.). Keep size reasonable for low latency.
prompt is optional; omit if not needed.

Response

Typical: { "result": { "text": "<transcript>" } }, or sometimes response/text. Errors return JSON { "error": "...", "detail"?: "..." } with HTTP codes (400/401/499/500).

Curl example (base64 to bytes inline)

# assumes AUDIO_B64 holds base64 of your audio (no data: prefix)
curl -X POST https://aiworker.linconwaves.com/flux-asr \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  --data "$(node -e \"const b=Buffer.from(process.env.AUDIO_B64,'base64'); console.log(JSON.stringify({audio:[...b],prompt:'Transcribe this clip'}));\")"

JavaScript (fetch)

const audioBytes = [82, 73, 70, 70];

const resp = await fetch('https://aiworker.linconwaves.com/flux-asr', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    Authorization: `Bearer ${process.env.API_KEY}`,
  },
  body: JSON.stringify({ audio: audioBytes, prompt: 'Transcribe this clip' }),
});

const data = await resp.json();
if (!resp.ok) {
  throw new Error(data.error || `Request failed (${resp.status})`);
}

const transcript =
  data.result?.text ||
  data.text ||
  data.response ||
  "No transcript found.";
