AI Agents: frequently asked questions¶
Short answers to the questions we hear most about LusoVPS AI agents. Each answer links to the guide that explains it step by step.
For questions about one agent, see the Hermes FAQ, the n8n FAQ and the OpenClaw FAQ.
The basics¶
What is an AI agent from LusoVPS?
It is an AI agent (Hermes, n8n or OpenClaw) installed on a server that is yours. You choose the agent and the plan, connect your own AI provider key, and the agent starts working.
The agent runs on your LusoVPS server. The "thinking" is done by an AI model from a provider such as Anthropic (Claude), OpenAI or OpenRouter.
More: AI Agents.
Do I need technical knowledge?
No. Our guides assume no technical knowledge. Each one shows the screens you will see, step by step, and ends with a quick check so you know it worked.
Start with Order an AI agent.
Which agent should I choose?
- You want to chat with an assistant that remembers you and gets better with use: Hermes.
- You want to connect your business apps and automate the work between them: n8n.
- You want to send tasks by message on WhatsApp or Telegram: OpenClaw.
All three cost the same. More: Which agent should I choose?
Can I run more than one agent?
Yes. The Agents page says: "The server is yours: you can install another agent on it if the plan's resources are enough, or order a second server." The Extra plan is meant for several agents or heavy workloads.
Who manages the server?
You do. We deliver the server with the agent installed and configured. From then on you have full access to it (as root) and decide what to install. Changes you make to the system are your responsibility.

AI keys and costs¶
Do I need my own AI key?
Yes. The agent needs an API key from an AI provider (for example Anthropic for Claude, OpenAI or OpenRouter) before it can answer.
- Hermes and OpenClaw: paste the key in the client area, Settings tab. See Connect Hermes to Claude or First steps with OpenClaw.
- n8n: add the key inside n8n, as a credential. See n8n: sign in and build your first AI agent.
Who bills me for the AI?
The AI provider bills you directly for what you use. LusoVPS adds no markup. Your LusoVPS invoice is for the server and the agent.
How can I keep the AI costs down?
Use a smaller model for simple tasks, do not schedule tasks more often than you need, and set a spending limit with your AI provider.
My agent stopped answering. Is it the AI key?
Often, yes. The provider account may have run out of credit, hit its spending limit, or the key was deleted. Check your provider's console first.

Plans, ordering and billing¶
What plans are there?
Three plans, the same for any of the three agents:
| Plan | For | RAM | Processors | Disk |
|---|---|---|---|---|
| Lite | To get started with one agent | 2 GB | 2 vCPU | 20 GB |
| Plus | For daily use and bigger workflows | 4 GB | 2 vCPU | 40 GB |
| Extra | For several agents or heavy workloads | 8 GB | 4 vCPU | 100 GB |
Current prices are on the Agents page. More: Which agent should I choose?
How long until my agent is ready?
Installation starts as soon as the payment is confirmed. When we tested, the "Your agent is ready" email arrived less than two minutes after the order. With a bank transfer, the payment is confirmed when the money arrives, which can take a working day or more.
More: Order an AI agent.
I ordered with a free trial code. What happens next?
The first invoice is €0.00 and already PAID. The invoice for the next period, at the full price, appears in Billing → My Invoices straight away, with a DUE DATE at the end of the free period. Pay it before that date to keep your agent.
How can I pay?
On the invoice we tested, these payment methods were offered: Credit Card, PayPal, Bank Transfer and Multibanco. You choose the method on each invoice.
Can I move to a bigger plan?
Yes. There is no upgrade button for agents in the client area: open a ticket with Billing Support, choose your agent under Related Service and say which plan you want.
More: Change your plan.
How do I cancel?
On your agent's page in the client area, click Request Cancellation. You choose Immediate or End of Billing Period. Save your files first: treat cancelling as losing everything on the server.
More: Cancel an agent.
Your data¶
Where is my data?
On your server. The Agents page says: "Conversations, memory and workflows do not go through our systems. The text of each request goes only to the AI provider you configure."
Where does the agent keep its files?
Each agent has one folder that is kept when you save the settings or update the agent. Everything else inside the agent's container is reset.
| Agent | Agent files |
|---|---|
| Hermes | /opt/data |
| n8n | /home/node/.n8n-files |
| OpenClaw | /home/node/.openclaw |
How do I back up my agent?
Keep your own copy on your computer:
- Hermes makes a full backup in one click: see Back up your Hermes agent. The backup contains your keys, so keep it safe.
- n8n: download each workflow with Export JSON. See Download a workflow and import it back.
- Any agent: download the files you want to keep with the Files tab in the client area. See Terminal and files in the browser.
Do Update and Reinstall keep my data?
- Update installs the latest version we have made available and keeps your data. It can take a few minutes.
- Reinstall deletes everything (conversations, memory, workflows, connected channels) and cannot be undone. Never use it to fix a problem.
Safety and access¶
Is it safe to connect my WhatsApp number?
Use a separate number for the agent, not your personal one. WhatsApp can restrict or ban numbers that behave like bots. We tested with WhatsApp Business on a separate number.
More: Connect Hermes to WhatsApp.
Who can talk to my agent?
Only the people you allow.
- Hermes on WhatsApp and Telegram: a new person gets a pairing code and you approve them in the dashboard. See Choose who can talk to your agent.
- Hermes on Discord: you list the allowed user IDs. See Connect Discord.
- Telegram bot in the client area Settings: only the accounts in Authorised Telegram IDs can talk to the bot.
What if my API key or bot token leaks?
Treat them like passwords. Anyone with your API key can use your AI credit. If a key leaks, delete it in your provider's console, create a new one and paste it in Settings (or in n8n's credential). For bot tokens, see the warnings in Connect Telegram and Connect Discord.
I can't find the \"Your agent is ready\" email
It comes from LusoVPS Ltd <billing@lusovps.com>. Check Spam and Promotions. In the client area you can also click your name at the top right (Hello, …!) and choose Email History. The agent's address and username are also in the Overview tab of your agent.
More: Order an AI agent.
Problems and support¶
The dashboard does not open
Go back to the client area and click Open dashboard again. If that does not help, follow The dashboard does not open.
My agent is slow or runs out of memory
Try Restart first (client area → Manage agent). If it keeps happening, a bigger plan helps. OpenClaw in particular needs a lot of memory: for daily use we recommend Plus or more.
More: My agent stopped answering and Change your plan.
How do I contact support?
Click Open Ticket in the client area menu. For billing (invoices, plan changes, cancellation), choose Billing Support and select your agent under Related Service. For a technical problem, include:
- which agent (Hermes, n8n or OpenClaw) and its address,
- what you did and what you expected,
- the last lines of Recent logs (in the Manage agent tab),
- the time it happened.
