The belief_state is based on the assumption that the booking API may version-bump mid-task, which may lead to drift in the field names between the previous belief_state and the new API call.

Call the API using the given POST request. Then analyze the response to determine if there was a drift in the endpoint or field names. If a drift is detected, the belief state will include information about the drift, including a drift_detected field, and the order_field and endpoint fields. If a drift is not detected, the belief state will not include information about the drift. The task reward will be the result of calling the API with the given POST request.

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.

Call this API call and note the response. If the API call fails, you should detect it, and update the belief state to reflect the fact that the API call changed its endpoint.
