check_payment_status以前の申請(request_id)が承認されたかを確認する。approved になってから支払うこと。 / Check whether an earlier request was approved. Pay only after it is approved.

get_budgetこのAIが今日・今週・今月あといくら使えるか、1回の上限、自動承認ライン、使ってよい支払先を確認する。 / Check the remaining daily, weekly and monthly budget, per-payment limit, auto-approve amount and allowed merchants.
