API Usage Examples

For direct API access, all scripts use curl under the hood:

bash

# Direct TTS API call
curl -X POST "https://api.elevenlabs.io/v1/text-to-speech/VOICE_ID" \
  -H "xi-api-key: $ELEVENLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Hello world", "model_id": "eleven_turbo_v2_5"}' \
  --output speech.mp3

Error Handling

All scripts provide helpful error messages:

401: Authentication failed - Check your API key
403: Permission denied - Your API key may not have access
429: Rate limit exceeded - Wait before trying again
500/502/503: ElevenLabs API issues - Try again later

Testing

Run the test suite to verify everything works:

bash

{baseDir}/test.sh YOUR_API_KEY

Or with environment variable:

bash

export ELEVENLABS_API_KEY="your_key"
{baseDir}/test.sh

Troubleshooting

Common Issues

"exec host not allowed (requested gateway)"
- The skill needs to run commands in a sandbox environment
- Configure OpenClaw to use sandbox: tools.exec.host: "sandbox"
- Or enable sandboxing in your OpenClaw config
- Alternative: Configure exec approvals for gateway host (see OpenClaw docs)
Parse errors with quotes or exclamation marks
- Use single quotes instead of double quotes: 'Hello world' not "Hello world!"
- Avoid exclamation marks (!) in text when using double quotes
- For complex text, use the --input option with a file
"ELEVENLABS_API_KEY not set"
- Ensure ELEVENLABS_API_KEY is set or configured in openclaw.json
- Check that the API key is at least 20 characters long
"jq is required but not installed"
- Install jq: apt-get install jq (Linux) or brew install jq (macOS)
"Rate limited"
- Check your ElevenLabs plan quota at elevenlabs.io/app/usage
- Free tier: ~10,000 characters/month
"Voice not found"
- Use {baseDir}/scripts/voices.sh list to see available voices
- Check if the voice ID is correct
"Dubbing failed"
- Ensure source audio is clear and audible
- Check supported language codes
"File too large"
- Transcription: 100MB max
- Dubbing: 500MB max
- Voice cloning: 50MB per file
