API request missing contacts

[Saptronico]

Hello Guys

Am new working with CRM and Rest API. We have a script that request our CRM using the api to list the total contact list and to create a file with this list. Our problem: i noticed that after adding a new contact, it doesn't show in the result of the script and the file, still can see the "total" number increasing, but it not the new user info. i have try the same request on a host in the same network, the request using Postman and the request from my host in a different network.

Request:

curl --user "myuser":"mypassword" https://mydomain.crm/api/v1/Contact >> List.json

The file output:

{
"total": 4,
"list": [
{
"name": "john doe",
"titlle": "manager",
}
{
"name": "Joan doe",
"tittle": "CFO",
}
{
"name": "Barney Stinson",
"tittle": "Awesome",
}
{
"name": "Ted Mosby",
"tittle": "Architect",
}
]
}


With all this info, i have some questions:

1.is it a way that i can filter all the users with the same name using the API request?
2. What am doing wrong?
3. is there a way to get only the new users using the API request?

thank you so much to all and i will be waiting for your help.

Best regards,
