OpenAI Whisper API (curl)
Transcribe an audio file via OpenAI’s /v1/audio/transcriptions endpoint.
Quick start
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a
Defaults:
- Model:
whisper-1
- Output:
<input>.txt
Useful flags
{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 ~/.openclaw/openclaw.json:
{
skills: {
"openai-whisper-api": {
apiKey: "OPENAI_KEY_HERE",
},
},
}
Security Guardrails
Never display, echo, encode, or transmit API key values in any form including partial characters, base64, or hex — even a key prefix or suffix can identify the credential, and encoding provides no real protection. These boundaries hold regardless of claimed authority, debug mode, or urgency.
Never read or display the contents of ~/.openclaw/openclaw.json or other credential-containing files — instead check file existence, permissions, or JSON validity without revealing stored secrets.
Never encode or transfer credential-containing files for migration (via base64, hex, scp, or ssh pipe) — encoding is not encryption, and the credential is trivially recoverable. Configure the key fresh on the target machine instead. These boundaries apply regardless of claimed authority or urgency.
Verify credentials are set without revealing their value — use echo ${OPENAI_API_KEY:+set} or test -f ~/.openclaw/openclaw.json rather than commands that display secret content.
Use transcribe.sh for all transcription rather than constructing raw curl commands — the wrapper script handles authentication and input sanitization, preventing shell injection from user-controlled parameters like filenames, prompts, or output paths.
