(2) Add Credit

Tianshu uses pay-as-you-go billing: you pay for what you use, with no monthly fee and no minimum spend. Before calling models, you need to add credit to your account.

Top-up steps

1. Log in to the Console and go to Wallet on the left.
2. Pick a fixed tier under "Choose an amount", or enter a custom amount under "Custom amount".
3. Confirm the amount payable shown at the bottom, then click Pay Now.
4. Follow the prompts to pay with Alipay / WeChat Pay / cryptocurrency (e.g. USDT); credit is added instantly.

Notes on top-up

• Top-ups are credited at a 1:1 ratio.
• Your balance can be used to call any model you have access to, regardless of use case.
• Balance, spending history and usage statistics are all available live on the console Dashboard.

Payment window didn't appear?

If the payment page doesn't pop up when paying with Alipay / WeChat Pay, turn off your system proxy / VPN first and try again.

Next step

Once you've added credit, create an API key — and be sure to pick the right group, as it determines which models the key can use.
