I got the patent application notice and found an agent online. Is there any way to tell the truth from the false? Can you find it in the National Patent Office?

If you get the original paper copy of the patent acceptance notice stamped with the statement of the Intellectual Property Office, which proves that you have paid the relevant fees, you can ask the agency to send you the receipt issued by the Intellectual Property Office. If you apply for an invention patent, when it enters the substantive examination stage and becomes public, you can use the application number to collect your patent on the website of the Intellectual Property Office. If it is a patent for utility model or design, it can only be found online after authorization!
