When your credit balance is running low, or you need more credits to power intensive AI work, you can purchase credit top-up packs at any time to recharge.

​
What Are Top-Up Packs

Top-up packs are a one-time credit recharge method. You select a denomination, complete the payment, and the corresponding credits are credited to your account instantly. No waiting, no subscription required. Unlike subscription plans, top-up packs are not recurring — you buy on demand and top up again when needed.

​
Purchase Process

1

Go to the Top-Up Page

Click your avatar in the top-right corner → select “Billing,” then find the “Top Up Credits” or “Top-Up Packs” option on the page.
2

Choose a Denomination

Six default denominations. The base rate is a constant 100 credits per ¥1; bonus credits start at the ¥30 tier.
3

Confirm Payment

After confirming your purchase, select a payment method and complete the transaction.
4

Credits Credited

After successful payment, credits are immediately added to your account and ready to use.

​
Default denominations

Stability: configurable defaults. The table is the zero-config fallback in code; operations can override denominations and bonus rates via system_config.recharge_plans. When overridden, the top-up page is authoritative.The 1:100 base rate is identical at every tier — buying bigger only improves the bonus, never the base rate. So if you only need 1,000 credits, the ¥10 tier and a larger tier are equivalent on the base portion.

​
Base Credits vs. Bonus Credits

Each top-up pack consists of two parts: Purchased base credits never expire, so you can accumulate them with confidence. The consumption priority deducts bonus credits before purchased ones automatically, so you never need to manually “spend the bonus first.”

​

​
Top up a workspace

A top-up is recorded on the current workspace. Switch to that workspace in the sidebar first.
Can buy a top-up pack for this workspace’s pool. Base credits and bonus credits both enter that pool, and people in the workspace spend them.
Members cannot top up. The page tells them to ask a workspace admin.
Each workspace has one pool. A top-up lands in the current workspace, not in another one. See Plans and credits.

FAQ

Once credits are credited to your account, refunds are not supported. Please confirm the denomination you need before purchasing.
Plan bonus credits are automatically granted with your subscription and have an expiration date. Top-up packs require manual purchase, and their base credits never expire. They also differ in consumption priority — top-up bonus credits are consumed before purchased credits, which are used last.
Yes, purchases accumulate. But unpaid orders have a concurrency cap — creating a new order while too many are still pending is rejected with RECHARGE_TOO_MANY_PENDING (HTTP 429). Pay off or let the earlier orders expire first.
Top-up packs are a paid-subscriber entitlement. Free users are rejected with RECHARGE_REQUIRES_PAID_SUBSCRIPTION.Workspace members face a second restriction: RECHARGE_WORKSPACE_ADMIN_ONLY — workspace credits are topped up by an administrator, so a regular member cannot top up that pool.
