}List API key usage
Returns AI spending by API key. Use kind to distinguish individual keys from grouped usage, including requests without API key authentication.
With project_reference, returns usage for the project’s keys and requests without a key. Without it, returns the caller’s own keys and requests without a key. Project listings also include usage from deleted key records. Account listings cannot recover that usage after the record identifying the key’s owner is deleted.
Usage comes directly from the AI usage ledger. usd is the customer charge for credits at the credit rate; it does not expose provider cost.
