How to Search

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

CODEBLOCK0

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

Search Parameters

• - q: Keyword search (required)
• INLINECODE2: Filter by niche (e.g., "dental", "fitness")
• INLINECODE3: Filter by category
• INLINECODE4: "landscape", "portrait", or "square"
• INLINECODE5: Results per page (max 100)
• INLINECODE6: Page number for pagination
• INLINECODE7: Set to "true" for random results

Response Format

The API returns JSON with this structure:

CODEBLOCK4

Handling Empty Search Results

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

CODEBLOCK5

When you receive suggestions, do the following:

1. 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. 2. Suggest alternative keywords if alternativeKeywords is not empty:

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

1. 3. 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:

CODEBLOCK6

Response:
CODEBLOCK7

• - 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

CODEBLOCK8

Request body:

• - prompt (required): Description of the image to generate (minimum 10 characters)
• INLINECODE15 (optional): Niche category for the image

Response:
CODEBLOCK9

Step 2: Poll for Status

Generation takes 25-120 seconds. Poll every 15-20 seconds:

CODEBLOCK10

Status values:

• - pending - Queued for generation
• INLINECODE17 - Currently being created
• INLINECODE18 - Done! Image URLs available
• INLINECODE19 - Generation failed
• INLINECODE20 - Took too long

Completed response:
CODEBLOCK11

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)
• INLINECODE22 — Direct download link for the image (use this for all "Download" links)
• INLINECODE23 — 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

CODEBLOCK12

Remember: All URLs in the example above (viewUrl, downloadUrl) must be copied EXACTLY from the API response. Do NOT generate or guess any URLs.
