# Venice Transcription (`/audio/transcriptions`)
`POST /api/v1/audio/transcriptions` takes an audio file and returns text. It's OpenAI-compatible with `multipart/form-data` — the OpenAI SDK's `audio.transcriptions.create()` works unchanged.
## Use when
- You need STT (speech-to-text) for voice notes, meetings, podcasts, short audio.
- You need timestamps for subtitles / chapters.
- You want to pick between fast local-style models (Parakeet) and large multilingual ones (Whisper, Wizper, Scribe).
For long video / YouTube transcription, see [`venice-video`](../venice-video/SKILL.md)'s `/video/transcriptions` (takes a public video URL directly).
## Minimal request
```bash
curl https://api.venice.ai/api/v1/audio/transcriptions \
-H "Authorization: Bearer $VENICE_API_KEY" \
-F "file=@./meeting.m4a" \
-F "model=nvidia/parakeet-tdt-0.6b-v3" \
-F "response_format=json" \
-F "timestamps=false"
```
```json
{ "text": "Alright everyone, let's kick off the meeting..." }
```
With `timestamps=true`, `json` format also returns segment/word timings (schema is model-specific).
## Request (`multipart/form-data`)
| Field | Type | Default | Notes |
|---|---|---|---|
| `file` | binary | — | **Required.** Audio file. Supported: `wav`, `wave`, `flac`, `m4a`, `aac`, `mp4`, `mp3`, `ogg`, `webm`. Base64 is **not** accepted — upload as a real file. |
| `model` | enum | `nvidia/parakeet-tdt-0.6b-v3` | See models below. |
| `response_format` | `json` / `text` | `json` | `text` returns `text/plain` body. |
| `timestamps` | bool | `false` | Include segment/word timestamps (JSON only). |
| `language` | string | — | ISO 639-1 hint (e.g. `en`, `ja`). Only Whisper-family models honor it; others auto-detect. |
## Models
| Model ID | Notes |
|---|---|
| `nvidia/parakeet-tdt-0.6b-v3` | Default. Fast, English-first, great for real-time-ish flows. |
| `openai/whisper-large-v3` | Large multilingual, honors `language` hint. |
| `fal-ai/wizper` | Whisper variant, competitive on quality/latency tradeoff. |
| `elevenlabs/scribe-v2` | ElevenLabs Scribe, strong on noisy audio. |
| `stt-xai-v1` | xAI Speech-to-Text. |
`GET /models?type=asr` returns the current catalog. ASR pricing is `pricing.per_audio_second.usd` — cost scales with audio duration.
## OpenAI SDK
```ts
import OpenAI from 'openai'
import fs from 'node:fs'
const client = new OpenAI({
apiKey: process.env.VENICE_API_KEY,
baseURL: 'https://api.venice.ai/api/v1',
})
const out = await client.audio.transcriptions.create({
file: fs.createReadStream('meeting.m4a'),
model: 'openai/whisper-large-v3',
response_format: 'json',
language: 'en',
// @ts-expect-error — Venice-specific extra, passes through multipart
timestamps: true,
})
console.log(out.text)
```
## Batch / long files
Venice doesn't expose native chunking. For files > ~30 min, split client-side on silence with `ffmpeg` or `pydub`, transcribe each chunk, then concatenate with offset timestamps.
```bash
ffmpeg -i long.mp3 -f segment -segment_time 600 -c copy chunk_%03d.mp3
```
## Errors
| Code | Meaning |
|---|---|
| `400` | Bad params, unsupported audio format, empty file, or **file larger than 25 MB** (this endpoint returns `400` with `"Maximum size is 25MB"`, not `413`). |
| `401` | Auth / Pro-only. |
| `402` | Insufficient balance. |
| `415` | Wrong `Content-Type` — must be `multipart/form-data`. |
| `422` | Validation / upstream ASR error (e.g. zero-length audio, upstream provider 422). Not a "content policy" code on this path. |
| `429` | Rate limited. |
| `500` / `503` | Transient; retry with jitter. |
## Gotchas
- `file` must be uploaded as a real multipart file part. JSON + base64 is **not** supported here.
- Timestamps are only surfaced in the JSON response shapes (`json`, `verbose_json`, `srt`, `vtt`). With `response_format: text` the handler returns a plain `text/plain` body containing just the transcript — you'll lose any timestamp data, so pick `verbose_json` / `srt` / `vtt` when you need timings.
- `language` is Whisper-specific. Parakeet / Scribe ignore it and auto-detect.
- Peak concurrency limits apply — on `429`, back off; big batches should throttle to ~5 parallel requests.
- Content-policy rejection on the transcript is returned as `422` with an error string; it does not surface `suggested_prompt` on this path.

Review before install: Avoid automatic install
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.
