How Billing Works

TensorX uses a prepaid credit system. You add credits to your account and pay only for what you use based on token consumption.

Cost = (Input Tokens × Input Price) + (Output Tokens × Output Price)

Balance Management

Minimum Balance Requirement

Important: When your balance falls below $0.05, your account and API keys will be automatically disabled to prevent negative balance.

You must top up your account to re-enable access.

Low Balance Notifications

You'll receive notifications when your balance is running low:

• Email alerts sent automatically at a fixed low-balance threshold
• Dashboard warnings when balance is low

Re-enabling Your Account

If your account has been disabled due to low balance:

1. Log in to app.tensorx.ai
2. Add credits to your account
3. Your API keys will be automatically re-enabled once your balance is above $0.05

Pricing

Pricing is based on token usage. Each model has different rates for input and output tokens.

View Current Pricing: tensorx.ai/models

All pricing is displayed per 1M tokens.

How to Estimate Costs

• 1 token ≈ 4 characters of English text
• 100 tokens ≈ 75 words
• A typical API request with a short prompt and response might use 500-2000 tokens

Cost Optimization Tips

1. Choose the right model - Use smaller/faster models for simple tasks
2. Set max_tokens - Limit output length when appropriate
3. Use system prompts efficiently - Keep them concise
4. Cache responses - Don't repeat identical queries
5. Monitor usage - Check your dashboard regularly

---

Refund Policy

24-hour refund window. If you need a refund, contact [e-mail] within 24 hours of your purchase. After 24 hours, all purchases are final and credits become non-refundable.

We recommend starting with a small amount to test the platform before making a larger purchase.

FAQ

Do credits expire?

No, credits do not expire. Use them whenever you need.

Can I get an invoice?

Yes, every top-up generates an invoice you can download yourself:

1. Sign in to the dashboard.
2. Open Billing from the sidebar.
3. In the Recent Transactions list, click the Invoice button next to the deposit you want.

The invoice opens in a new tab with a Download PDF option.

What happens when I run out of credits?

When your balance falls below $0.05, your account and API keys will be disabled. API requests will return authentication errors. Add credits to re-enable your account.

Is there a minimum purchase?

Check tensorx.ai for current minimum purchase amounts.

Can I set up auto top-up?

Yes. Auto top-up is self-serve from your dashboard. You set two values:

1. A trigger balance — when your credit balance falls to this amount, a top-up is made automatically.
2. A refill amount — the amount of credit added each time the trigger is reached.

No support request is needed to switch it on or off.
