Volcengine
v1.0.0Configure and use Volcano Engine models like Doubao, GLM, Kimi, and DeepSeek via OpenClaw for general, coding, and troubleshooting tasks.
Like a lobster shell, security has layers — review code before you run it.
Volcengine Skill
Configure and use Volcano Engine (Volcengine) models with OpenClaw. This skill covers both general-purpose models and specialized coding models through Volcengine's OpenAI-compatible API endpoints.
Quick Start
1. Get API Key
- Sign up at Volcano Engine Console
- Navigate to Access Key Management
- Create a new API key with appropriate permissions
- Copy the API key (format:
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx,无需添加sk-前缀)
2. Configure OpenClaw
Interactive setup (recommended)
openclaw onboard --auth-choice volcengine-api-key
Follow the prompts to enter your API key.
Manual config (openclaw.json)
Add to your openclaw.json:
{

"defaults": {
"models": {
"volcengine/doubao-seed-1-8-251228": {
"alias": "Doubao"
},
"volcengine-plan/ark-code-latest": {
"alias": "ArkCode"

Usage Examples
Using via CLI
# Use Doubao model
openclaw --model Doubao "Hello, summarize this text"
# Use Ark Code for programming
openclaw --model ArkCode "Write a Python function to sort a list"
# Use full model reference
openclaw --model volcengine/doubao-seed-1-8-251228 "Explain quantum computing"
Setting Default Model
# Set Doubao as default
openclaw configure --set agents.defaults.model.primary volcengine/doubao-seed-1-8-251228
# Set Ark Code as default for coding tasks
openclaw configure --set agents.defaults.model.primary volcengine-plan/ark-code-latest
Advanced Configuration
Environment Variable
For better security, use environment variables:
# Set in your shell profile
export VOLCANO_ENGINE_API_KEY=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx # 火山引擎密钥无需添加sk-前缀
# Reference in config
"apiKey": "VOLCANO_ENGINE_API_KEY"

Troubleshooting
Common Issues
-
Authentication failed
- Verify API key is correct
- Check if key has necessary permissions
- Ensure key is not expired
-
Connection timeout
- Verify network connectivity to
ark.cn-beijing.volces.com - Check firewall settings
- Try different region endpoint
- Verify network connectivity to
-
Model not found
- Verify model ID spelling
- Check if model is available in your region
- Ensure you're using correct provider (volcengine vs volcengine-plan)
-
Rate limiting
- Check API usage quotas
- Implement retry logic with exponential backoff
- Consider upgrading plan for higher limits
Testing Connection
# Test with curl
curl -X POST https://ark.cn-beijing.volces.com/api/v3/chat/completions \
-H "Authorization: Bearer $VOLCANO_ENGINE_API_KEY" \
-H "Content-Type: application/json" \
-d '{

Best Practices
-
Model Selection
- Use
volcengine-plan/*for coding tasks - Use
volcengine/*for general conversation - Consider context window size for long documents
- Use
-
API Key Security
- Never commit API keys to version control
- Use environment variables
- Rotate keys periodically
- Quota Limit: Each account supports up to 50 API Keys
- Permission Control: Restrict keys to specific Model IDs or IP addresses
- Project Isolation: Keys only work within their project space
-
Error Handling
- Implement retry logic for transient failures (429, 500, 502, 503, 504)
- Log errors for debugging
- Set up alerts for quota limits
- Handle sensitive content detection errors (400 series)
- See Error Codes for complete list
-
Performance
- Use streaming for long responses
- Adjust temperature for creativity vs consistency
- Set appropriate max_tokens to control response length
-
Authentication Methods
- API Key (Recommended for most users): Simple bearer token authentication
- Access Key (Enterprise): HMAC-SHA256 signature-based auth for fine-grained permissions
- See Configuration Guide for details
