• receiving, by the API server from the validation server, a validation response to the authorization request, the validation response including a validation result based on the API authorization identifier and an indicator of a level of resources to be used when performing the request;
• and
• performing, by the API server, the service based on the request and the validation response.

• a memory that stores instructions;
• and
• one or more processors that are coupled to the memory and, when executing the instructions, are configured to:
• receive, from a client device, a request to access a service;
• transmit, to a validation server, an authorization request including an API authorization identifier;
• receive, from the validation server, a validation response to the authorization request, the validation response including a validation result based on the API authorization identifier and an indicator of a level of resources to be used when performing the request;
