Cost
2 credits per call, whether it is run from the site or from the API — the credential differs, the price does not. A new account starts with 20 credits.
A rejected request still costs a credit: the authorizer decrements before the tool validates. A call rejected for a missing or invalid key is free.
Parameters
Generated from the endpoint’s own validation, so this is exactly what it accepts. A body field goes at the top level; an option goes inside options.
