# Frequently Asked Questions

## 1. What does a `0.3x` billing multiplier mean?

The multiplier determines how much AnyRoute balance is deducted relative to the model provider's official USD price.

For example:

> If the official model charge is **US$1** and your group uses a `0.3x` multiplier, the request deducts **0.3 AnyRoute balance** (equivalent to ¥0.30).
>
> Using an illustrative exchange rate of US$1 ≈ ¥7, this is about **4.3% of the official RMB-equivalent cost**.

A lower multiplier means a lower usage cost. Multipliers vary by group, so choose a group that fits your model, performance, and availability requirements.

## 2. How is the actual charge calculated?

```text
Actual deduction = official model price in USD × group billing multiplier
```

Example: if a request has an official price of US$0.50 and the selected group uses a `0.3x` multiplier:

> Actual deduction = US$0.50 × 0.3 = **0.15 AnyRoute balance**

You can review the detailed charge for each request under **Usage Records** in the console.

## 3. How do groups differ, and which one should I choose?

Groups may differ in:

- **Billing multiplier:** a lower multiplier reduces the balance deducted for the same official model charge.
- **Supported models:** some groups support only specific models.
- **Availability and speed:** concurrency limits and response times may vary.

For general use, start with the recommended group shown in the console. Choose a dedicated group when you have stricter stability or performance requirements.

## 4. Can I create multiple API keys?

Yes. You can create multiple keys on the **API Keys** page to separate projects or use cases. Each key can be managed independently, while all keys share the same account balance.

## 5. How is service stability maintained?

AnyRoute uses:

- Continuous 24/7 system monitoring
- Capacity planning based on usage
- Failover and automated recovery mechanisms
- Ongoing optimization for high-frequency development workloads

## 6. How do I recharge or purchase balance?

AnyRoute uses an account-balance model. After recharging, API usage is deducted from your balance according to the model token prices displayed by AnyRoute.

Open the recharge page in either of these ways:

1. Sign in and select **Recharge** in the console balance area.
2. Visit [https://cc.anyroute.io/purchase](https://cc.anyroute.io/purchase) after signing in.

Recharge flow:

1. Select an amount. The minimum recharge is ¥10.
2. Confirm the payment method.
3. After payment succeeds, return to AnyRoute; the balance is credited automatically.
4. Review your balance, orders, and per-request charges in the console.

If a successful payment is not credited, email [support@anyroute.io](mailto:support@anyroute.io) and include the order number, account email, payment time, and payment amount.

For the complete flow, see [Recharge your balance](https://en-guide.anyroute.io/9233163m0.md#recharge-your-balance).

## 7. Can I request an invoice?

Yes. We recommend requesting an invoice only after the corresponding balance has been fully consumed.

Once an invoice is issued, the invoiced amount is treated as reported revenue for tax purposes. If you request a refund after asking for an early invoice, tax may already have been incurred.

- If the tax cost results from a customer-side request, such as requesting a refund after an early invoice, the customer is responsible for the related **5% tax charge**.
- If the refund or issue is caused by AnyRoute, AnyRoute is responsible for the tax charge.

In short: consume the balance first, then request the invoice.
