Rate Limits & Billing

The API uses pay-as-you-go billing. You're charged per request.

Pricing​

FeatureCost per Request
AI Assistant$0.15
Deep Research$0.20

How It Works​

  1. Add funds to your account in the Developers page
  2. Each request deducts the cost from your balance
  3. Monitor usage in real-time on the dashboard

Insufficient Balance​

If your balance is too low, you'll get a 402 error:

{
  "error": {
    "type": "insufficient_balance",
    "message": "Please add credits to your account",
    "details": {
      "balance_before_cents": 5,
      "cost_cents": 10
    }
  }
}

Solution: Go to Developers → Balance and add funds.

Auto-Recharge​

Never run out of balance:

  1. Go to Developers → Balance
  2. Enable Auto-Recharge
  3. Set threshold (e.g., $10) and reload amount (e.g., $50)

When your balance drops below the threshold, we'll automatically charge your payment method.

Rate Limits​

If you have a subscription plan, you may have monthly usage limits. When exceeded, you'll get a 429 error:

{
  "error": {
    "type": "rate_limit_exceeded",
    "message": "Monthly usage limit reached",
    "details": {
      "reset_at": "2025-11-01T00:00:00Z"
    }
  }
}
