I use the web service by python code ( Is there in any way to give the constrain like field of view, pixel size or magnitude?

Best regards,

If you run
    python3 -h
you will get the help message.

To give the image size, you want to use "--scale-units", "--scale-lower", and "--scale-upper".

For example, to say that your pixel scale is between 1.0 and 1.2 arcseconds per pixel,

--scale-units arcsecperpix --scale-lower 1.0 --scale-upper 1.2


                        Units for scale estimate ("arcsecperpix",
                        "arcminwidth", "degwidth", or "focalmm")
                        Scale lower-bound
                        Scale upper-bound
