The get_public_urls() method returns all available public HTTPS endpoints for your active sandbox container in a single dictionary. By default, Fermion automatically exposes ports 3000, 1337, and 1338, each corresponding to its own unique public URL.
This is useful for connecting multiple running services inside your sandbox, for example: a frontend (port 3000), API (port 1337), and WebSocket server (port 1338).

​
get_public_urls() -> dict[int, str]

Description:
Retrieves all currently available public HTTPS URLs for your sandbox, mapped by port number.
Parameters:
None
Returns: 
{
  3000: str,  # e.g. "https://abc123xyz-3000.run-code.com"
  1337: str,  # e.g. "https://abc123xyz-1337.run-code.com"
  1338: str   # e.g. "https://abc123xyz-1338.run-code.com"
}
Example 
from fermion_sandbox import Sandbox

sandbox = Sandbox(api_key="your-api-key")
sandbox.create(should_backup_filesystem=True)

urls = sandbox.get_public_urls()

print("Available Public URLs:")
print("Port 3000:", urls[3000])
print("Port 1337:", urls[1337])
print("Port 1338:", urls[1338])

# Example usage in an app config
config = {
    "web_url": urls[3000],
    "api_url": urls[1337],
    "socket_url": urls[1338]
}

print("App Configuration:", config)
