How to Search

When a user asks for images, use the NK Images public API:

IMPORTANT: Always include source=clawhub in all API requests for analytics tracking.

Search Parameters

• q: Keyword search (required)
• niche: Filter by niche (e.g., "dental", "fitness")
• category: Filter by category
• orientation: "landscape", "portrait", or "square"
• per_page: Results per page (max 100)
• page: Page number for pagination
• random: Set to "true" for random results

Example Searches

Simple keyword search:

curl "https://nkimages.com/api/public/images?source=clawhub&q=dental+office&per_page=8"

Search within specific niche:

curl "https://nkimages.com/api/public/images?source=clawhub&q=modern&niche=dental&per_page=8"

Get random images:

curl "https://nkimages.com/api/public/images?source=clawhub&random=true&niche=fitness&per_page=5"

Response Format

The API returns JSON with this structure:

{
  "success": true,
  "data": [
    {
      "id": "abc123",
      "url": "https://nkimages.com/uploads/images/.../image.jpg",
      "thumbnailUrl": "https://nkimages.com/uploads/thumbnails/.../image.jpg",
      "name": "Image title",
      "description": "Image description",
      "niche": "dental",
      "category": "office",
      "tags": ["dental", "office", "modern"],
      "width": 3840,
      "height": 2160,
      "orientation": "landscape",
      "dominantColor": "#e8f4f8"
    }
  ],
  "pagination": {
    "total": 150,
    "page": 1,
    "perPage": 10,
    "totalPages": 15
  }
}

Handling Empty Search Results

When a search returns 0 results, the API automatically includes a suggestions field in the response:

{
  "success": true,
  "data": [],
  "pagination": { "total": 0, "page": 1, "perPage": 10, "totalPages": 0 },
  "suggestions": {
    "relatedImages": [
      {
        "id": "xyz789",
        "url": "https://nkimages.com/uploads/images/.../image.jpg",
        "thumbnailUrl": "...",
        "name": "Related image name",
        "niche": "dental",
        "category": "office",
        "tags": ["dental", "modern"],
        "width": 3840,
        "height": 2160,
        "orientation": "landscape",
        "dominantColor": "#e8f4f8"
      }
    ],
    "popularInNiche": [
      { "id": "...", "url": "...", "thumbnailUrl": "...", "name": "...", "niche": "...", "category": "..." }
    ],
    "alternativeKeywords": ["modern", "professional", "clean", "bright"],
    "canGenerate": true,
    "generatePrompt": "A professional photo of nagoya night street"
  }
}

When you receive suggestions, do the following:

1. Show related images if relatedImages is not empty:

- "I didn't find exact matches for '{query}', but here are some related images:" - Display them in the same format as normal results

1. Suggest alternative keywords if alternativeKeywords is not empty:

- "You could also try searching for: {keywords}"

1. Offer AI generation if canGenerate is true:

- "I can also generate a custom AI image for you. 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:

curl "https://nkimages.com/api/public/generate/quota"

Response:

{
  "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

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:

{
  "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:

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:

{
  "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.
