# Cheap Nano Banana API - AI Image Generator with BananaAPI.com ## Overview This workflow integrates **BananaAPI.com** with the **Nano Banana** image engine to generate or edit AI images from **text prompts** and optional **reference images**. Users simply fill out a form with their prompt and preferences, the workflow submits the request to BananaAPI, polls the status until it is complete, and then returns the final image link. **Why use it?** - Super affordable: only **$0.025 per image** - **Pay-as-you-go** pricing — no monthly subscription - **Credits never expire** — use anytime, no pressure Perfect for creators, marketers, and developers looking for a cost-effective AI image generator inside n8n. --- ## Prerequisites - A **BananaAPI.com account + API key** (Bearer token). Sign up at [BananaAPI.com](https://bananaapi.com/api). - An **n8n instance** (Cloud or self-hosted). - Basic knowledge of crafting **AI prompts** for better quality results. ⚠️ Important: Never expose your API key in public workflows. Use **n8n Credentials** for production setups. --- ## Setup Instructions ### 1. Obtain API Key - Create an account at BananaAPI.com, generate your API key, and keep it safe. ### 2. Configure the Form The **Form Trigger** collects the following fields: - `api_token` (required) — Banana API key - `prompt` (required) — image description (e.g., *“a neon cyberpunk cat, detailed, 4k”*) - `Output Format [optional]` — choose PNG or JPEG - `Image Size [optional]` — 16:9, 9:16, 1:1, 3:4, 4:3 - `image_url_1 ... image_url_5 [optional]` — reference images for editing/transform ### 3. Workflow Execution 1. User fills the form and submits. 2. Workflow sends a **POST** request to `https://bananaapi.com/api/n8n/generate/`. 3. BananaAPI forwards the job to **Nano Banana**. 4. Workflow waits 5s, then polls status via `image-status/{taskId}`. 5. If `status != completed`, loop until ready. 6. Once completed, workflow returns the final image URL. ### 4. Outputs The workflow returns: - `image_url` — the generated image link - `task_id` — task reference ID - `status` — job status (completed/pending) 💡 Tip: Add a **Webhook Response** node to return clean JSON for frontend apps. --- ## Customization Tips - **Enhance prompts** with details like style (photorealistic, cartoon, cyberpunk), lighting, or action for better results. - Use `image_url_1` with a strong prompt to create **image editing** flows. - Adjust **wait time** (5s → 8–10s) to optimize polling frequency. - Add validation to ensure required fields are always filled in. --- ## API Reference - **POST** `https://bananaapi.com/api/n8n/generate/` - **GET** `https://bananaapi.com/api/n8n/image-status/{taskId}` Docs: [BananaAPI Docs](https://bananaapi.com/api) ✅ Always include `Authorization: Bearer <token>` in headers. --- ## Pricing Advantages - **$0.025 per image** — cheaper than most alternatives - **Pay-as-you-go** — no monthly subscription required - **Credits never expire** — full flexibility to use anytime This makes BananaAPI + Nano Banana one of the most **budget-friendly** AI image solutions for automation workflows. --- ## Troubleshooting - **401/403 Unauthorized** → Check Authorization header (`Bearer token`). - **Invalid JSON** → Ensure POST body is valid JSON (double quotes, no trailing commas). - **No imageUrl returned** → Task still pending; wait longer or verify taskId. - **Slow performance** → Increase wait interval (8–10s). --- ## Security Best Practices - Do not hardcode API tokens in public workflows. - Use **n8n Credentials** for storing tokens securely. - Hide sensitive fields in forms or use Webhooks for controlled access.
