API prices per model
API usage is paid from a prepaid balance in US dollars. Each request is charged for the tokens it uses, at 50% of the official Anthropic price.
Creating an API key needs the Hosted plan ($9 / month). Usage is charged on top of that, from the balance you top up in the console.

- A price change applies to requests made after it. Requests already billed keep the price they were billed at.
- Every request and its cost is listed in the console under Usage log.
