Kimi API offers free trial credits to newly registered users, allowing you to fully explore the platform's capabilities before committing.

Trial credits

• Eligibility: New users who register with an email address.
• Credit Amount: A $2 credit voucher is granted upon registration.
• Validity: The voucher is valid for 3 months from the date of issuance and expires automatically thereafter.

Use your voucher

• The voucher is automatically applied to API usage — no manual activation required.
• Voucher balance is consumed before any topped-up balance.
• You can check your remaining voucher balance on the "Billing Details" page in the console.

What can $2 get you?

The $2 trial credit is sufficient for extensive development testing, for example:

• Hundreds of standard chat requests
• Dozens of long-document parsing calls
• Thorough API integration testing and feature validation

The exact number of calls depends on the model selected and the token consumption per request.

After the voucher is used up

Once the voucher is depleted, API calls will be charged against your topped-up balance. If your balance is zero, API requests will return a 403 error. You can top up at any time in the console — funds are available immediately.
