The API monitor tool is designed for monitoring API and COM interface, it can detect dll's API, analyze the symbols automatically with pdb files, monitor input/output parameters, and provides source code level monitoring. It is easy to use and efficient in monitoring.

What sets this software apart from others like it, such as ApiSpy or API monitor tools, is that it doesn't require any development of DLL or hook DLL. Users can enjoy a seamless experience without any additional work.
The software has several noteworthy functions, including VBScript or JScript to control Auto Debug, source code level monitor, automatic analysis parameter type with pdb files, an easy way to generate pdb files without source code if you know the API prototype, supporting tracing COM and activex interface, supporting monitor multi-thread, supporting spying the parameters of function before and after the function is called, supporting the function that the target program will dump CallStack when an exception occurs, and finally, supporting plugin technology.
Users can customize input and output formats as well, without needing to know the prototype of the functions. All the API functions, including the opened functions that are called inside the DLL, can be monitored.
In conclusion, this software is a fantastic tool for monitoring APIs and analyzing program errors. Its unique features set it apart from others in the market and make it a valuable asset for developers.
