Failure to add params to endpoint

Hello guys while trying to make a simple script i have encountered an error and i've scratched google's head and mine but didn't find a solution . So the problem is anytime i run this code i get a response from the server saying ' the api-key is missing' instead of giving me info on the number i enter i dont know if i'm doing anything wrong btw . Any help would you be appreciated This is a sample of my code

import requests
list = input('Input Phone Numbers List :')
link = "http://apilayer.net/api/validate"
head = {'User-agent': 'user-agent-here'}
s = requests.session()
session = s.get(link,headers=head)
phone = open(list, 'r')
while True:
    num = phone.readline().replace('\n', '')
    if not num:
        break
    cot = num.strip().split(':')
    send = s.post(link,
    data={'access_key':'1135810505585d6e034f640fbf30a700','number':cot[0]},headers=head,)
    (stats, respond) = (send.status_code, send.text)
    print (stats, respond)

Example on numverify.com shows that it needs GET request so it needs values as get(..., params=...) but at start (before while True) you use get() without any parameters - and it makes problem.

You don't need post() and (as in most API) you don't need headers, and cookies.

import requests

#list = input('Input Phone Numbers List :')

link = "http://apilayer.net/api/validate"

payload = {
    'access_key': '1135810505585d6e034f640fbf30a700',
    'number': '',
}

#phone = open(list, 'r')
phone = ['+14158586273', '+46123456789']

for num in phone:
    num = num.strip()
    if num:
        cot = num.split(':')
        
        payload['number'] = cot[0]
        
        response = requests.get(link, params=payload)
        
        print('status:', response.status_code)
        print('text:', response.text)
        print('---')
        
        data = response.json()
        
        print('number:', data['international_format'])
        print('country:', data['country_name'])
        print('location:', data['location'])
        print('carrier:', data['carrier'])
        print('---')
        
        
        

Result:
