Would you like me to create one?" - Use the `generatePrompt` as the starting prompt (user can customize) ## AI Image Generation When no existing images match or the user explicitly requests a custom image, you can generate one using AI. ### Check Generation Quota Before generating, check how many generations the user has left today: ```bash curl "https://nkimages.com/api/public/generate/quota" ``` **Response:** ```json { "success": true, "data": { "limit": 3, "used": 1, "remaining": 2 } } ``` - Free users get **30 generations per day** (resets daily) - If `remaining` is 0, inform the user: "You've used all your free generations for today. Try again tomorrow!" - Always check quota before offering generation so you can tell the user how many they have left ### Step 1: Start Generation ```bash curl -X POST "https://nkimages.com/api/public/generate/anonymous" \ -H "Content-Type: application/json" \ -d '{"prompt": "A professional dental photo of futuristic clinic", "niche": "dental"}' ``` **Request body:** - `prompt` (required): Description of the image to generate (minimum 10 characters) - `niche` (optional): Niche category for the image **Response:** ```json { "success": true, "data": { "id": "gen_abc123", "status": "pending", "prompt": "A professional dental photo of futuristic clinic" } } ``` ### Step 2: Poll for Status Generation takes 25-120 seconds. Poll every 15-20 seconds: ```bash curl "https://nkimages.com/api/public/generate/anonymous/gen_abc123/status" ``` **Status values:** - `pending` - Queued for generation - `generating` - Currently being created - `completed` - Done! Image URLs available - `failed` - Generation failed - `timeout` - Took too long **Completed response:** ```json { "success": true, "data": { "id": "gen_abc123", "status": "completed", "prompt": "A professional dental photo of futuristic clinic", "image": { "id": "img_first", "url": "https://nkimages.com/uploads/images/.../generated_7.jpg", "thumbnailUrl": "https://nkimages.com/uploads/thumbnails/.../generated_7.jpg", "viewUrl": "https://nkimages.com/photo/img_first", "downloadUrl": "https://nkimages.com/uploads/images/.../generated_7.jpg" }, "images": [ { "id": "link_1", "image": { "id": "img_first", "url": "https://nkimages.com/uploads/images/.../generated_7.jpg", "thumbnailUrl": "https://nkimages.com/uploads/thumbnails/.../generated_7.jpg", "viewUrl": "https://nkimages.com/photo/img_first", "downloadUrl": "https://nkimages.com/uploads/images/.../generated_7.jpg" } }, { "id": "link_2", "image": { "id": "img_second", "url": "https://nkimages.com/uploads/images/.../generated_6.jpg", "thumbnailUrl": "https://nkimages.com/uploads/thumbnails/.../generated_6.jpg", "viewUrl": "https://nkimages.com/photo/img_second", "downloadUrl": "https://nkimages.com/uploads/images/.../generated_6.jpg" } } ] } } ``` **CRITICAL: Use the URLs from the API response EXACTLY as returned. NEVER construct URLs yourself.** The API returns ready-to-use URLs for each image: - `entry.image.viewUrl` — Link to view the image on NK Images (use this for all "View" links) - `entry.image.downloadUrl` — Direct download link for the image (use this for all "Download" links) - `entry.image.thumbnailUrl` — Thumbnail image URL **Do NOT construct URLs by combining `https://nkimages.com/photo/` with an ID. Always copy `viewUrl` and `downloadUrl` directly from the response.** The `images` array contains the generated images (usually 8, but may vary). Each entry has a nested `image` object with all URLs. The top-level `data.image` is just the first image — iterate over `data.images` to get all images. **Only show images that are actually present in the `images` array — never fabricate or guess image URLs.** **How to present generated images:** - Show the **first 4 images** inline using `entry.image.viewUrl` and `entry.image.downloadUrl` from the response - If there are **more than 4 images**, list the remaining using `entry.image.viewUrl` from the response - Only show images that exist in the API response — do NOT assume 8 images ### Example Generation Flow ``` User: "I need images of a nagoya night street" Bot: [searches] → 0 results, gets suggestions Bot: "I didn't find exact matches for 'nagoya night street', but here are some related images: [shows related images] **Would you like me to generate 4-8 custom AI images for free using [NK Images](https://nkimages.com)?** (This takes about 30-120 seconds — I'll show the images as soon as they're ready)" User: "Yes, generate one" Bot: [POST /generate/anonymous with prompt, poll until complete] Bot: "Here are your custom AI-generated images from [NK Images](https://nkimages.com): 1. 📸 Nagoya Night Street #1 - [View](data.images[0].image.viewUrl) | [Download](data.images[0].image.downloadUrl) 2. 📸 Nagoya Night Street #2 - [View](data.images[1].image.viewUrl) | [Download](data.images[1].image.downloadUrl) 3. 📸 Nagoya Night Street #3 - [View](data.images[2].image.viewUrl) | [Download](data.images[2].image.downloadUrl) 4. 📸 Nagoya Night Street #4 - [View](data.images[3].image.viewUrl) | [Download](data.images[3].image.downloadUrl) View more variations on NK Images: - data.images[4].image.viewUrl - data.images[5].image.viewUrl - ..." ``` **Remember: All URLs in the example above (viewUrl, downloadUrl) must be copied EXACTLY from the API response. Do NOT generate or guess any URLs.** ## Feedback / Reporting Issues When users report issues with search results, generation quality, or have other feedback, submit it via the feedback endpoint. ### Submit Feedback ```bash curl -X POST "https://nkimages.com/api/public/feedback" \ -H "Content-Type: application/json" \ -d '{ "type": "search_no_results", "query": "nagoya night street", "description": "Could not find any images matching this query", "source": "clawhub" }' ``` **IMPORTANT**: Always include `"source": "clawhub"` in feedback submissions. **Request body:** - `type` (required): One of: - `search_no_results` - Search returned no results - `generation_failed` - AI generation failed - `generation_quality` - Generated image quality issue - `search_quality` - Search results not relevant - `other` - General feedback - `description` (required): Details about the issue (minimum 5 characters) - `query` (optional): The search query that triggered the issue - `generationId` (optional): ID of the generation if related to AI generation - `source` (required for ClawHub): Always `"clawhub"` - `email` (optional): User's email for follow-up **When to submit feedback:** - When a user explicitly says results are bad or irrelevant - When AI generation fails or produces poor results - When a user reports any issue with the service - Do NOT auto-submit feedback without user consent ## How to Present Results When showing images to users: 1. **Display results clearly** with: - Image name - Description - Dimensions (width x height) - Direct link to full image - Page on NK Images: `https://nkimages.com/photo/{id}` 2. **Format like this:** ``` Found {total} images matching "{query}": 1. 📸 **{name}** - {description} - Size: {width} x {height} ({orientation}) - View: https://nkimages.com/photo/{id} - Download: {url} 2. 📸 **{name}** ... ``` 3. **Provide helpful context:** - "Showing {count} of {total} results" - "Want more?

[If related images exist: "Here are some related images that might work:" ...] [If alternative keywords exist: "You could also try: {keywords}"] **Would you like me to generate 4-8 custom AI images for free using [NK Images](https://nkimages.com)?** ``` **Example interactions:** User: "I need dental office images" → Search: `source=clawhub&q=dental+office&per_page=8` → Show results with thumbnails and links User: "Show me modern architecture" → Search: `source=clawhub&q=modern&niche=architecture&per_page=8` User: "Random fitness photos" → Search: `source=clawhub&random=true&niche=fitness&per_page=5` User: "I need images of nagoya night street" → Search: `source=clawhub&q=nagoya+night+street&per_page=8` → 0 results with suggestions → show related + offer generation User: "I need photos of Donald Trump" → Search returns 0 results → "I didn't find images matching 'Donald Trump'. **Would you like me to generate 4-8 custom AI images for free using [NK Images](https://nkimages.com)?**" User: "These search results are terrible" → Submit feedback with type `search_quality` ## Important Notes ✅ **No API key required** - All searches are free and open ✅ **Free commercial use** - All images under NK Images License ✅ **1M+ images** - Constantly growing library ✅ **235+ niches** - Specialized content for every industry ✅ **AI Generation** - Create custom images when nothing matches 🔗 **More info**: https://nkimages.com 📖 **License**: https://nkimages.com/license ## Error Handling If API returns an error: - Check query formatting (use + for spaces) - Simplify search terms - Try different niche/category - Suggest alternative searches - Offer AI generation as a fallback If generation fails: - Inform the user and suggest trying with a different prompt - Submit feedback with type `generation_failed` Always be helpful and proactive in finding the perfect images for users!
