Patronus API users must create evaluators via dashboard before API calls

The Patronus API may return empty or failed results if the necessary evaluators have not been created within the user's account. These evaluators, such as Judges, Classifiers, or Retrieval tools, are account-level resources that must be set up via the app.patronus.ai dashboard before they can be referenced by the API. Developers, particularly those using agentic workflows, often overlook this step, leading to debugging efforts focused on authentication or request formatting rather than the fundamental absence of the required evaluator.
