It first defines the prompt, sends it to the MuAPI predictor, then extracts the resulting image URL for downstream use or viewing.\n\n### Setup steps\n\n- **Requirement:** Install the `n8n-nodes-muapi` community node in your n8n instance (Settings -> Community Nodes).\n- Configure the MuAPI credentials/API key required by the MuAPI Predictor node.\n- Edit the Set Prompt node to define the text prompt and any required input fields for the model.\n- Verify the MuAPI Predictor node is set to the intended Nano Banana 2 Pro model or endpoint.\n- Run the workflow manually with Execute Workflow and inspect the extracted image URL output.\n\n### Customization\n\nChange the prompt text, model parameters, image size, style, or output field mappings to generate different images or return additional response data."

About this workflow

This manual workflow generates an image from a text prompt using the MuAPI Nano Banana 2 Pro text-to-image model, then extracts the generated image URL so you can view it or pass it to downstream steps. Runs when you manually execute the workflow in n8n. Sets a text prompt to…
