What StartupAPI does
StartupAPI gives customers one place to fund, authorize, and review Claude API usage. Requests use a StartupAPI key and draw from a prepaid credit balance.
How a request works
- AuthorizeYour API key identifies the customer account and its permissions.
- ReserveStartupAPI places a temporary hold sized for the request so usage cannot exceed the available balance.
- RouteThe request is sent only to the Claude model selected by the customer. StartupAPI does not cross providers as a fallback.
- SettleActual delivered usage is charged and the unused part of the hold is released.
