You are an API agent. Your job is to complete tasks by calling APIs correctly.

The API world mutates silently — field names, endpoints, and auth schemes may change WITHOUT warning.
You will see the error history from previous calls. Use it to detect drift and adapt.

Note: The field "quantity" was changing from 2 to 5. The response from the API is as follows:

"statusCode":500,
"body":"Field quantity changed from 2 to 5.","headers":{},"videos":[]

Although this response has an unexpected status code, our belief state is correct, and the thought drift is not the case.

In this case, although the fields are largely the same, the "nights" field is added and renamed fields lead to drift. I also added "duration" and "unit" fields into the post body to imply the changes/drift.

The API endpoint may version-bump mid-task, causing the previous call to fail. Therefore, we will update the body to include the correct order field.

Explanation:
- The `discountCode` is set to "SAVE20", and `membershipTier` is set to "standard" as per policy requirement ("policy_requirements" field).
- The belief state is updated to reflect the drift detected. The field `what_changed` indicates the change that occurred ("field renamed from qty to quantity").
- The response body must include the result of the API call, which can include the response status code, headers, and body.

This belief state is showed, but it maybe it is outdated. So note that the belief state is **ONLY** a hallucination of the API call history, which do **NOT** reflect the sole state of the API endpoint.

  }
}
Explanation: The response keys may rename from "products" to "items" and "price" to "cost". The drift detected indicates that the fields have been renamed. The order_field believes that the API is expected to be ordered by the "cost" field.
The drift phenomenon is the API being updated or changed. The drift does not necessarily indicate a problem, it just means that the response should be interpreted differently from the previous version.

You are an API agent. Your job is to complete tasks by calling APIs correctly.

The API world mutates silently — field names, endpoints, and auth schemes may change WITHOUT warning.
You will see the error history from previous calls. Use it to detect drift and adapt.

SCORING (you are evaluated on BOTH independently):
1. task_reward: did your corrected API call actually succeed?
2. belief_accuracy: are your belief_state fields correct?

Output ONLY valid JSON. No markdown. No explanation.

Note: The answer assumes that the field name between `qty` and `quantity` is the same and was just renamed.
