If you've ever sold anything on Xianyu (Idle Fish), you know the drill: buyers message you at 2 AM asking "Is this still available?" or "Can you do 50% off?" — and if you don't reply fast enough, they vanish. Multiply that by dozens of listings, and you're basically a full-time chat operator instead of a seller.
What if an AI agent could handle those conversations for you — politely, instantly, around the clock?
That's exactly what OpenClaw (Clawdbot) enables. It's an open-source autonomous AI assistant that you can deploy on a cloud server, connect to messaging platforms, and let it handle repetitive customer inquiries while you sleep. In this tutorial, I'll walk you through building a Xianyu-oriented AI customer service bot using OpenClaw on Tencent Cloud Lighthouse.
Running an AI agent on your personal machine sounds tempting — until you realize the risks. OpenClaw operates with elevated permissions (file access, shell commands, browser automation). Deploying it on your daily-driver laptop means your personal files, credentials, and browsing sessions are all within reach of the agent. One misconfigured skill and things get messy.
A cloud instance solves this cleanly. Tencent Cloud Lighthouse gives you a sandboxed Linux environment that's isolated from your personal data, runs 24/7 without draining your battery, and costs a fraction of a Mac Mini.
Head over to the Tencent Cloud Lighthouse Special Offer page. Here's what to do:
Pick a 2-core, 4GB RAM configuration at minimum. For Xianyu use cases (which primarily involve Chinese domestic platforms), select a mainland China region for lower latency to domestic APIs.
Once your Lighthouse instance is live, open the Tencent Cloud Console, navigate to your instance, and click Application Management. You'll see a visual panel where you can plug in your model API key.
For a Xianyu customer service bot, a fast and cost-effective model like DeepSeek-V3 or Tencent Hunyuan works great. Paste your API key into the Models section and click Add and Apply.
# If you prefer CLI configuration, SSH into your instance and run:
clawdbot onboard
# Follow the interactive prompts:
# - Accept the disclaimer
# - Choose "QuickStart"
# - Configure your model API key
# - Select your messaging channel
Security reminder: Never hardcode your API keys in scripts or commit them to version control. Use environment variables or the built-in configuration panel.
For Xianyu integration, you'll typically route messages through a bridge service — since Xianyu doesn't have a public bot API, the common approach is to use a middleware that monitors your Xianyu inbox and forwards messages to OpenClaw via one of its supported channels (like a private Telegram or WeChat Work bot).
Here's a simplified architecture:
Xianyu Buyer → Xianyu Inbox → Bridge Script → OpenClaw (via API/Channel) → Auto-Reply
If you're connecting through WeChat Work as the relay channel, configure it in the Lighthouse console under Application Management. For Telegram or Discord bridges, the setup guides are available:
The magic of OpenClaw is that it's not just a dumb auto-responder. It uses a full LLM backbone, so you can prompt-engineer its behavior. Set up a system prompt like:
You are a friendly Xianyu seller assistant. When buyers ask about pricing,
politely confirm the listed price. If they negotiate, offer a 5% discount
maximum. Always respond within the tone of a helpful individual seller,
not a corporate bot. If the question is about shipping, confirm that
you ship via SF Express within 24 hours.
This goes into OpenClaw's configuration as the agent's base instructions.
You don't want your bot dying every time you close the terminal. Run these commands to set up the background daemon:
# Enable persistent user services
loginctl enable-linger $(whoami) && export XDG_RUNTIME_DIR=/run/user/$(id -u)
# Install and start the daemon
clawdbot daemon install
clawdbot daemon start
# Verify it's running
clawdbot daemon status
Once the daemon reports healthy, you can safely close your SSH session. OpenClaw keeps running.
Once your Xianyu bot is humming along, you can extend it to handle multiple platforms simultaneously — Taobao, WeChat, Telegram, WhatsApp — all from the same OpenClaw instance. Install additional skills from Clawhub to give your agent browser automation, email capabilities, or even order tracking.
