Kalle by Appmake API · Reference

Pricing

The API is billed per token and paid from your workspace's prepaid balance.

Base URLhttps://api.kalle.build/v1AuthBearer kalle_sk_…VersionKalle-Version: 2026-11-01

Prices per million tokens

Kalle Turbo$0.05$0.25
Kalle Design$1$5
Kalle Turbo Max$1$5
Kalle Turbo Ultra$2$10

Prices are the same figure in euros for a workspace billed in euros. Higher effort makes the model write more reasoning tokens, which are billed as output. Failed requests and token counting are free.

Kalle Browser tasks started through the API use the workspace's credits, like the same task started in Appmake.
