Credits & Balance

This page explains how credits, account balance, top-ups, bills, redemption codes, and reward balance work in SynStar AI.

SynStar AI uses a prepaid credit system. Before making API requests, your account needs to have enough available credits. Credits are deducted automatically when you use supported models and services.

What Are Credits?

Credits are the prepaid balance in your SynStar AI account.

Credits are denominated in USD and are used to pay for API usage across supported models and services.

$1 credit = $1 account balance

Credits can be used for supported APIs, including:

• Text and chat models
• Vision models
• Image generation
• Video generation
• Audio transcription
• Text-to-speech
• Music and voice generation
• Embeddings
• Rerank models
• Other supported model APIs

Wallet Management

You can manage your balance from the Wallet Management page in the Console.

The Wallet Management page may include:

• Current balance
• Total consumption
• Number of requests
• Top-up options
• Payment method selection
• Recharge amount selection
• Bills and top-up records
• Redemption code recharge
• Invite reward balance

This page helps you track how much credit you have, how much has been consumed, and how your balance changes over time.

Account Statistics

The account statistics panel shows a quick overview of your account usage.

Common fields include:

Field	Description
Current Balance	The remaining available credits in your account
Consumption	The total amount of credits consumed by API usage
Number of Requests	The total number of API requests made by your account

These statistics help you quickly understand your account status before running new API requests.

Top-Up Credits

When you top up your account, the paid amount is added as base credits.

$1 paid = $1 base credit

For selected top-up amounts, bonus credits may also be added to your account.

Your total credited balance may include:

Total Credits = Base Credits + Bonus Credits

Top-Up Rewards

SynStar AI may provide bonus credits for selected recharge amounts.

Payment Amount	Base Credits	Bonus Credits	Total Credits Added	Bonus Rate
$10	$10	$0	$10	0%
$50	$50	$0	$50	0%
$100	$100	$3	$103	3%
$500	$500	$20	$520	4%
$1,000	$1,000	$100	$1,100	10%
More than $1,000	Payment amount	12% bonus	Payment amount × 1.12	12%

Examples:

Top up $100 = receive $103 credits
Top up $500 = receive $520 credits
Top up $1,000 = receive $1,100 credits
Top up $2,000 = receive $2,240 credits

Bonus credits are added to your account balance and can be used for API usage just like regular credits, unless otherwise stated.

Bonus credits cannot be withdrawn as cash and may be subject to platform policies.

Payment Methods

SynStar AI supports online top-ups through supported payment providers.

Airwallex is used as one of our payment service providers for online recharge processing. Available payment methods may depend on your country, region, currency, card issuer, and payment provider rules.

Depending on your account and region, available payment methods may include:

• Credit card
• Debit card
• Other payment methods supported by Airwallex
• Other payment methods shown on the recharge page

The actual payment options available to you will be displayed on the Wallet Management page when you top up your account.

How to Top Up

To top up your account:

1. Go to the Console.
2. Open Wallet Management.
3. Enter the top-up quantity or select a recharge amount.
4. Select an available payment method.
5. Complete the payment through the supported payment provider.
6. After the payment is successful, credits will be added to your account balance.

Credits are usually added automatically after successful payment.

If your payment succeeds but credits do not appear in your account, please contact support with your account email and payment details.

Recharge Amounts

The recharge page may provide predefined recharge amounts, such as:

Recharge Amount	Description
$10	Basic top-up amount
$20	Small top-up amount
$50	Medium top-up amount
$100	Eligible for bonus credits
$200	Larger balance top-up
$500	Eligible for bonus credits

The available recharge amounts may change depending on platform settings, payment provider availability, and promotional rules.

If you need a larger custom top-up amount, please contact support.

Bills and Top-Up Records

You can view your top-up records from the Bills section.

The Bills page may include:

Field	Description
Order No.	The top-up order number
Payment Method	The payment method used for the order
Top-Up Quota	The credits or quota added to the account
Payment Amount	The amount paid
Status	The current payment or top-up status
Creation Time	The time when the order was created

Bills help you check whether a payment was successful, pending, failed, or completed.

If there is no record, the page may show that no charge records are available.

Payment Status

A top-up order may have different statuses.

Common statuses may include:

Status	Meaning
Pending	The payment has been created but not completed yet
Paid	The payment was successful
Completed	Credits have been added to your account
Failed	The payment failed or was declined
Cancelled	The payment was cancelled
Refunded	The payment was refunded

The exact status labels may vary depending on the payment provider and system settings.

Redemption Code Recharge

SynStar AI may support redemption code recharge.

If you have a valid redemption code, you can enter it on the Wallet Management page to add credits or promotional balance to your account.

To redeem a code:

1. Go to Wallet Management.
2. Find the Redemption Code Recharge section.
3. Enter your redemption code.
4. Click Redeem.
5. If the code is valid, the corresponding credits will be added to your account.

Redemption codes may have restrictions, such as:

• Expiration date
• Usage limit
• Account eligibility
• Region restrictions
• Promotional rules

If a redemption code does not work, please check whether the code is correct, still valid, and eligible for your account.

Invite Rewards

SynStar AI may provide invite rewards for eligible referral activities.

The Invite Reward section may show:

Field	Description
Proceeds to be Used	Reward amount available to transfer or use
Total Revenue	Total accumulated reward revenue
Number of People Invited	Number of users invited through your invitation link

You may also see an invitation link that can be shared with others.

Invite rewards may need to be transferred to your account balance before they can be used. If a transfer function is available, you can use it to move eligible reward amounts into your balance.

Invite reward rules may vary depending on promotion settings, referral conditions, and account eligibility.

Balance Deduction

Credits are deducted automatically when you make API requests.

The deducted amount depends on:

• The selected model
• The endpoint used
• The actual token usage or task usage
• The model’s listed price
• The Token Group used by your API token
• The Billing Tier linked to that Token Group
• Any model-specific billing rules

You do not need to manually calculate the deduction for each request. SynStar AI calculates it automatically and records the final deduction in your usage history.

Account Balance vs Token Group

Account Balance and Token Group are different concepts.

Your account balance determines how many credits you have available.

A Token Group determines the billing rate applied when an API token is used.

Account Balance = how much credit you have
Token Group = how the usage cost is settled

For example, if your account has $100 credits and your API token belongs to a 0.3 billing group, eligible API usage with that token will be settled using the 0.3 billing rate.

The final cost is then deducted from your account balance.

Account Balance vs Token Quota

Account Balance and Token Quota are also different.

Item	Meaning
Account Balance	The total credits available in your account
Token Group	The billing rate group used for settlement
Token Quota	The maximum amount a specific API token is allowed to use

A token quota helps control how much a specific API token can consume.

If an API token has a custom quota, the token cannot spend more than that quota.

If an API token is set to unlimited quota, it means the token itself has no separate usage cap. Actual API usage is still limited by your account balance.

Unlimited quota does not mean unlimited free usage.

It only means that the API token has no separate quota limit.

Insufficient Balance

If your account balance is insufficient, API requests may fail or be rejected.

Common reasons include:

• Your account balance is too low
• The selected model requires more credits than your current balance
• A task-based API requires enough credits before task submission
• Your token quota has been reached
• Your account is under payment, risk, or compliance review

To continue using the API, you may need to top up your account or adjust your token quota.

Usage Records

You can view your credit usage records in the dashboard.

Usage records may include:

• Request time
• API token
• Token Group
• Model name
• Endpoint
• Input tokens
• Output tokens
• Cached tokens, if applicable
• Task usage, if applicable
• Billing rate
• Final credit deduction
• Request status
• Error information, if applicable

These records help you monitor spending, review model usage, and troubleshoot billing-related issues.

Balance Adjustments

In some cases, your balance may be adjusted manually or automatically.

Examples include:

• Bonus credits from top-up rewards
• Invite reward transfers
• Redemption code credits
• Refund adjustments
• Billing correction adjustments
• Promotional credits
• Manual support adjustments

If you believe your balance is incorrect, please contact support with your account email and relevant payment or usage records.

Refund and Credit Reversal

Used credits are generally non-refundable.

If a refund is approved for an unused top-up payment, the related credits may be removed from your account balance.

If bonus credits were granted for that payment, those bonus credits may also be removed.

If credits have already been used, the refund amount may be reduced or the refund request may be rejected according to our refund policy.

Best Practices

To manage your balance effectively:

• Check your balance before running large workloads.
• Review the model price before scaling usage.
• Use token quotas to control spending by API key.
• Use lower-cost models for simple or high-volume tasks.
• Monitor Bills and Usage Records regularly.
• Top up in advance to avoid request failures caused by insufficient balance.
• Keep payment receipts or transaction references for support requests.
