If you cannot connect to the Kasparex API, verify the endpoint URL is correct, check your network connection, ensure no firewall is blocking the connection, and verify the API service is operational.

If requests are timing out, check your network latency, verify the API server is not overloaded, and consider using a mirror node if available. You can also check the /api/stats endpoint for network health.

Most API endpoints are public and don't require authentication. Node registration and pings require a valid node ID. If you're having authentication issues, verify your node is properly registered.
