How I made $240 in one week with OpenClaw

I recently wanted to see what happens when you give an AI agent a real job.

The job was simple: sell my family's clothes on Vinted (basically Craigslist for clothes, popular in Europe). I had a pile of things I wanted to sell but never took the time to list them. So I wondered if an agent could run the entire workflow for me.

I connected OpenClaw to a Mac mini, and gave it access to a browser, my disk, and my emails. I talk to the agent through WhatsApp, so I can run the system from anywhere.

So far, the agent has generated around $240 of sales and created 11 listings.

The workflow

The process starts with me taking photos of a piece of clothing and sending them to the agent. From there, the agent does most of the work:

First, it uses the Manus API to adjust the photos and make them look more like ecommerce product images. It analyzes the photos and reads the labels to extract things like the brand, size, and materials. It also looks at the item visually to infer things like color, category, and sometimes even approximate dimensions.

Once it has all the information needed, it searches for similar listings to estimate the right price. Then it goes to the Vinted website and creates the listing itself. Title, description, price, photos, everything.

When buyers start messaging, the agent handles the conversation. If someone writes in Italian, Dutch, or English, it reads the message and replies in the same language. It also negotiates offers.

I gave it one simple rule: never accept an offer more than 10 percent below the listed price. The agent also monitors my email inbox. When Vinted sends notifications about messages or offers, it reads them and replies automatically.

The agent ordered its own shipping supplies

At some point I realized I was missing some basic materials for shipping. Instead of looking for them myself, I asked the agent to go on Amazon and add everything I needed to my cart. The agent browsed Amazon and selected a bunch of items like packaging materials and shipping supplies.

Honestly, I didn't review the selection. I was a bit lazy and just approved the order expecting something bad (wrong dimensions, poor quality, something like that). But so far everything it ordered has been perfectly usable. I ended up using every item it picked.

It felt like the agent was equipping itself with the tools needed to operate.

The agent designed the thank-you card

I also wanted to include a small thank-you card in each package. So I asked the agent to generate one. Instead of writing it directly, it used Manus to design a printable card thanking buyers for their purchase based on inspirations I shared. Now every package includes a small note generated by the agent itself.
