Fix: Venice AI 402 Billing Error
The "Silent Trap" of Venice AI
Venice AI returns a 402 Payment Required status when your balance is low. However, their error payload uses a nested structure: { "error": { "message": "insufficient usd..." } }. Older versions of OpenClaw look for specific strings at the root level, causing the gateway to hang or repeat the failed request instead of failing over to a backup provider like DeepSeek or OpenAI.
If your agents are stuck in an infinite loop or reporting "Unknown provider error" while using Venice, you are likely hitting a billing wall that isn't being caught by the fallback logic.
Next Step
Fix now, then reduce repeat incidents
If this issue keeps coming back, validate your setup in Doctor first, then harden your config.
Symptoms
Status: 402 (Payment Required)
Fix 1: Enable Strict Fallback Mapping
You can manually tell your agent to treat the Venice 402 error as a trigger to switch to the next model in your list. Update your openclaw.json:
"agents": {
"main": {
"model": ["venice/llama-3", "openai/gpt-4o"], // Fallback list
"config": {
"fallbackOnBillingError": true,
"billingErrorPatterns": ["insufficient usd", "402"]
}
}
}Fix 2: Add Auto-Topup via Venice API
To avoid these interruptions entirely, we recommend setting up a low-balance alert or auto-topup directly in the Venice AI console. Note that OpenClaw cannot currently recharge your account automatically.
Immediate Relief: Clear Cooldowns
If you have already topped up your account but OpenClaw still says "Rate limited" or "Billing error," the gateway is likely still in its cooldown period.
openclaw clear cooldown --provider venice\nopenclaw gateway restart
Did You Know?
Venice AI is excellent for uncensored workflows, but for routine tasks, switching to DeepSeek V3 as your primary model can reduce your daily spend by up to 70% while keeping Venice as a high-quality fallback.
