FAQ
Frequently asked questions about platform accounts, subscription billing, Lubei, and security, grouped by topic.
Account
Does one account work across all products?
Yes. A unified account system — register once and log in to all products (API, Lucrum, Switch, Creator, etc.), sharing your wallet balance and subscription plan.
How do I change my password?
Log in to identity.lurus.cn → Account Settings → Security → Change Password.
What if I forget my password?
Click "Forgot password" on the login page; a reset link will be sent to your registered email.
How do I delete my account?
Contact support@lurus.cn to close your account. All data (API keys / Lubei / transaction records) is permanently deleted and cannot be recovered.
Which third-party logins are supported?
GitHub and Google OAuth — link / unlink them in Account Settings.
Subscription & Billing
How do I upgrade / downgrade my plan?
Log in to identity.lurus.cn → Subscription Management → "Change Plan": upgrades take effect immediately with a prorated charge for the difference; downgrades take effect in the next billing cycle.
What happens when my subscription expires?
It is automatically downgraded to Free. Your API keys remain valid but are subject to Free-tier quotas; your data is retained and is restored when you renew.
What’s the difference between annual and monthly billing?
Annual plans are 20% off (≈ 2.4 months free); during the annual term you can upgrade but not downgrade.
How does the Enterprise plan add team members?
Admin Console → Team → Invite Member → enter an email and send the invitation → the member accepts and joins → you can assign each member a dedicated API key and quota.
Want the full quota and pricing rules?
Lubei
What is Lubei used for?
Paying for API calls beyond your subscription quota, subscribing to paid Lucrum strategies, and enjoying VIP discounts.
Does Lubei expire?
Purchased Lubei never expires; promotional Lubei may have an expiration date, subject to the rules of the promotion.
Can Lubei be withdrawn?
Unused Lubei bought via top-up is refundable; Lubei settled from Lucrum strategy income can be withdrawn to a bank card.
How do I check my balance and transaction history?
Log in to identity.lurus.cn → Wallet to view your current balance, income details (top-ups / rewards / strategy income), and spending details (API consumption / strategy subscriptions).
Payment
Payment methods:
Credit / debit card, worldwide
Cryptocurrency
Alipay / WeChat Pay, mainland China
What if my payment hasn’t arrived?
It is usually confirmed within 1 minute; if it hasn’t arrived after 5 minutes, check whether the payment platform charged you, look for a confirmation email, and contact support@lurus.cn with your payment order number.
How do I request an invoice?
Admin Console → Billing → Request Invoice (standard / special VAT invoice); it is usually emailed within one business day.
Security
Is my data secure?
HTTPS throughout (TLS 1.3); passwords stored with bcrypt encryption; payments handled by PCI DSS-compliant third parties; API call content is not stored (only metadata is recorded for billing).
What do I do if my API key is stolen?
Immediately disable the key in the console → create a new key → review the call logs to confirm any unusual usage → contact support to resolve any unexpected charges.
