# OpenAI Whisper API (curl)

Transcribe an audio file via OpenAI’s `/v1/audio/transcriptions` endpoint. Set `OPENAI_BASE_URL` to use an OpenAI-compatible proxy or local gateway.

## Quick start

```bash
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a
```

Defaults:

- Model: `whisper-1`
- Output: `<input>.txt`

## Useful flags

```bash
{baseDir}/scripts/transcribe.sh /path/to/audio.ogg --model whisper-1 --out /tmp/transcript.txt
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a --language en
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a --prompt "Speaker names: Peter, Daniel"
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a --json --out /tmp/transcript.json
```

## API key

Set `OPENAI_API_KEY`, or configure it in the active OpenClaw config file (`$OPENCLAW_CONFIG_PATH`, default `~/.openclaw/openclaw.json`). Optionally set `OPENAI_BASE_URL` (for example `http://127.0.0.1:51805/v1`) to use an OpenAI-compatible proxy or local gateway:

```json5
{
  skills: {
    "openai-whisper-api": {
      apiKey: "OPENAI_KEY_HERE",
    },
  },
}
```
