The method Consulta_RCCOOR doesn't work correctly. I changed the url in this way:
Original:
url = cls.base_url + "/OVCCoordenadas.asmx?op=Consulta_RCCOOR"
Change:
url = cls.base_url + "/OVCCoordenadas.asmx/Consulta_RCCOOR"
In my case, it works fine in that way (Python 3.6.8)

Hi, we noted a limit of downloads per hour. What is the limit?
Also we read this resolution, expressing the need for a mass downloading licence
http://www.catastro.minhap.gob.es/documentos/resoluciondgc20110323_tfs.pdf

Does it apply to PyCatastro? or only to download all data?

Thanks in advance

pycatstro v.0.1.3, Python 3.4:

from pycatastro import PyCatastro
PyCatastro.Consulta_RCCOOR("EPSG:4258",40,-4)

output:
