Quota System

How Quota Works

Each subscription includes a monthly quota that resets at the start of each billing cycle:

Cycle Start → Use Quota → Cycle End → Quota Reset
     ↓                         ↓
  Full Quota              New Cycle Begins

Quota Calculation

Quota is calculated based on token usage with model-specific multipliers:

Quota Used = Prompt Tokens + (Completion Tokens × Completion Multiplier)

PAYG (Pay-As-You-Go) Fallback

What is PAYG Fallback?

When your subscription quota is exhausted, PAYG fallback allows you to continue using the API by charging to your account balance:

Subscription Quota Exhausted → PAYG Kicks In → Continue Using API

Configuring PAYG

Setting	Description
Enable/Disable	Toggle PAYG fallback on or off
Spending Limit	Maximum PAYG spending per cycle
Current Spent	PAYG amount used this cycle

PAYG Spending Limits

Set a spending limit to control costs:

Example: Spending Limit = $50/month

If subscription quota runs out:
- PAYG activates
- Maximum $50 additional spending allowed
- After $50, requests will be rejected until next cycle

Subscription Lifecycle

Suspended	Temporarily paused (payment issue or manual)

Cycle Reset

At the start of each billing cycle:

1. Quota is reset to your plan's limit
2. PAYG spending counter resets to zero
3. Usage history is preserved for reporting

Payment Failure Handling

If a payment fails:

1. Grace Period: 3-7 days to resolve payment issue
2. Suspension: Subscription suspended if not resolved
3. Recovery: Automatic reactivation upon successful payment

2. Click Cancel Subscription
3. Choose cancellation timing:
   • Immediate: Ends now (no refund for remaining period)
   • End of Period: Continues until current cycle ends

After cancellation, your subscription API key will stop working at the end of the billing period.

Subscription vs. PAYG-Only

When to Use Subscription

• Predictable usage: You know your monthly needs
• Cost savings: Subscriptions offer better rates than pure PAYG
• Budget planning: Fixed monthly costs
• Consistent access: No need to top up balance

When to Use PAYG-Only

• Variable usage: Usage fluctuates significantly
• Testing phase: Evaluating the platform
• Low volume: Occasional API calls
• No commitment: Flexibility over savings

Auto Top-up

Enable automatic balance top-up to ensure uninterrupted service:

Setting	Description
Enable	Turn on auto top-up
Threshold	Balance level that triggers top-up
Amount	Amount to add when triggered
Payment Method	Card to charge

Example:
Threshold: $10
Amount: $50

When balance drops below $10 → Automatically charge $50 to your card

Dedicated Subscription Token

Each subscription comes with a dedicated API token:

• Format: sk-sub-xxxxxxxxxxxx
• Auto-sync: Quota automatically synced with subscription
• Cycle Reset: Token quota resets with billing cycle
• Separate from Regular Tokens: Managed independently

Using Your Subscription Token

from openai import OpenAI

client = OpenAI(
    api_key="sk-sub-your-subscription-key",
    base_url="https://api.apertis.ai/v1"
)

# Quota is tracked against your subscription
response = client.chat.completions.create(
    model="gpt-4.1",
    messages=[{"role": "user", "content": "Hello!"}]
)
