For practicing purposes I'm trying to retrieve data from https://www.ruc.com.py/ by posting the number 1000000

At first it retrieved a "no access" message so I added headers and that solved it. But now it just brings a blank result, I was expecting to get a the name that corresponds with the input 1000000

This is my code:

import requests

headers = {
'referer': 'https://www.ruc.com.py/',
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.60 Safari/537.36',
'x-requested-with': 'XMLHttpRequest'
}

num=str(1000000)

url = 'https://www.ruc.com.py/index.php/inicio/consulta_ruc'
response = requests.post(url , headers=headers, data=num)

print (response.text)
python-requests python

Had a look into the network tab from the website and found out that the POST payload requires the search to be on the form field buscar

With this, just had to do this small change to your code to actually send the payload with the expected data structure:

import requests

headers = {
'referer': 'https://www.ruc.com.py/',
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.60 Safari/537.36',
'x-requested-with': 'XMLHttpRequest'
}

data={"buscar": 1000000}

url = 'https://www.ruc.com.py/index.php/inicio/consulta_ruc'
response = requests.post(url, headers=headers, data=data)

print(response.json())
