Rate Limiting

Your API rate limit is based on your account tier. Your balance is checked separately before each request; it does not dynamically increase or decrease your RPM.

​
Account Tiers

Accounts are automatically assigned to a tier based on eligible successful payments.
TierEligibilityRPM
tier_0No eligible payment6
tier_1Eligible payments totaling at least $530
tier_2Eligible payments totaling at least $50, with first eligible payment more than 7 days ago120
tier_3Eligible payments totaling at least $250, with first eligible payment more than 7 days ago300
tier_4Eligible payments totaling at least $1,000, with first eligible payment more than 14 days ago600
Eligible payments are successful customer payments. Promotional credits, corrections, complimentary credits, and manual adjustments may not count toward automatic tier upgrades unless marked as eligible by PipeLLM.

​
Enterprise and Custom Limits

Enterprise customers can receive a custom RPM override. A custom override takes precedence over the automatic tier limit. Need higher limits? Contact us at hi-coding@pipellm.ai.

​
Balance Protection

To prevent unexpected overuse, the platform performs a real-time balance check before processing each request. If your balance is insufficient, the request will be rejected with a 402 status code.

​
Insufficient Balance Response (402)

{
  "error": {
    "type": "insufficient_balance",
    "code": "balance_exceeded",
    "message": "Insufficient balance. Please recharge to continue."
  }
}

​
Rate Limit Response (429)

  "error": {
    "type": "rate_limit_error",

    "message": "Rate limit exceeded. Your current limit is 120 requests per minute (approximately 2.00 requests per second). Please visit https://console.pipellm.com/billing to upgrade your plan for higher limits."
  }
}
