Get a free API key at **https://pixelfireman.com/account** and paste it into the **PixelFireman API** node (replace `YOUR_PIXELFIREMAN_API_KEY`, keep `Bearer `).\n2. In both **Google Sheets** nodes, connect your Google account and pick your spreadsheet + sheet.\n3. Your sheet needs a column named **prompt** (one prompt per row). The flow writes the result into an **image** column.\n4. Click **Test workflow**. Each row gets an image URL.\n\nCheap at volume: about $6.25 per 1,000 images, prepaid credits that never expire, failed renders never billed.\n\nDocs: https://pixelfireman.com/docs",
