Can anyone suggest me how can i use gns3 Api on python

Question

I've used cisco DevNet Sandbox. I'm facing errors while using napalm module python. And while I try to authenticate with the correct credentials it always tells me Authentication failed. So can I use Gns3 Api on python to overcome this issue regarding Cisco DevNet labs.

import napalm
import json

# CSR1000V
cisco_sandbox = {
   "hostname": " sandbox-iosxe-recomm-1.cisco.com",
   "port": 22,
   "username": "developer",
   "password": " C1sco12345",
}

NXOS = "nxos"
IOS = "ios"
NXOS_SSH = "nxos_ssh"

driver = napalm.get_network_driver(IOS)
if driver:
   connection = driver(
     hostname=cisco_sandbox["hostname"],
     username=cisco_sandbox["username"],
     password=cisco_sandbox["password"]
   )
else:
    connection = driver(
            hostname=cisco_sandbox["hostname"],
            username=cisco_sandbox["username"],
            password=cisco_sandbox["password"],
            optional_args={"port": cisco_sandbox["port"]}
        )

connection.open()
print(f"----- Connecting {cisco_sandbox['hostname']} on port {cisco_sandbox['port']}")
print(
    f"----- Device Facts:\n\t{json.dumps(connection.get_facts(), indent=4)}")
connection.close()
