元任务 AI 网关 uses a credit-based billing model: your account holds a balance, and each API request deducts credits proportional to the number of tokens processed. You can add credits at any time by topping up your balance, applying a promo code, or subscribing to a plan. Usage is metered in real time, so your balance reflects your current spending as requests complete.

​
View your balance

Your current credit balance is displayed in the dashboard. Log in at napi.origintask.cn and check the Balance or Account Overview section to see how many credits remain.
Monitor your balance regularly. If it reaches zero, API requests will be rejected until you top up.

​
Top up your balance

You can add credits to your account at any time from the dashboard.
1

Open the billing section

In the dashboard, navigate to Billing or Top Up (the label may vary by dashboard version).
2

Choose an amount

Select a preset top-up amount or enter a custom value, then proceed to payment.
3

Complete payment

Follow the on-screen instructions to complete the purchase. Credits are added to your balance immediately after payment is confirmed.

​
Apply a promo code

If you have a promo code, you can redeem it in the dashboard to receive bonus credits.
1

Open the promo code section

Navigate to Billing → Promo Code (or look for a Redeem Code option in the dashboard).
2

Enter your code

Type or paste your promo code into the input field and click Apply (or Redeem).
3

Confirm the credit addition

The dashboard confirms the redemption and shows your updated balance with the added credits.
Promo codes may have expiration dates or usage limits. Apply a code as soon as you receive it to ensure it is still valid.

​
Subscription plans

元任务 AI 网关 may offer subscription plans that provide better per-token rates, higher rate limits, or priority access to models. If subscription plans are available, you can find them in the Billing or Subscription section of the dashboard.
1

Browse available plans

Go to Billing → Subscription to see the plans on offer and compare their benefits.
2

Select a plan

Click Subscribe on the plan that fits your usage level and follow the payment steps.
3

Confirm your subscription

After payment, your subscription is activated. The dashboard reflects your new plan tier and any updated rate limits.

​
Check usage history

The dashboard provides a detailed view of your token consumption and spending over time.
  • Usage log — Each API request is recorded with the model used, tokens consumed, and credits deducted.
  • Spending summary — View aggregated spending by day, week, or month to understand your usage patterns.
  • Per-key breakdown — If you use multiple API keys, you can see usage attributed to each key.
To access usage data, navigate to Usage or History in the dashboard.

​
How usage is deducted

Credits are deducted in real time as each API request completes. The deduction is based on the number of input and output tokens processed by the model. Different models have different per-token rates — check the dashboard or the Available Models page for current pricing.
If your balance reaches zero mid-request, that request may fail. Keep a comfortable buffer in your balance to avoid unexpected interruptions, especially for high-volume workloads.
Set a calendar reminder to review your balance weekly, or use the usage history to forecast how long your current balance will last based on recent consumption.
