Supported Image Formats

• PNG
• JPG / JPEG
• GIF
• WebP

Maximum file size: 20 MB

Dependencies

This skill requires:

• curl: Usually built-in

Processing Flow

1. Parse Arguments

• Parse --image (required): determine if it's a local file or URL
• Parse --prompt (required): the question about the image

2. Check User Credits

• Call /api/v1/auth/me to get user info
• Vision uses post-deduct billing (2 base credits + token cost)
• Requires minimum balance

3. Send Vision Request

• If image is a URL: use POST /api/v1/ai/vision with JSON body
• If image is a local file: use POST /api/v1/ai/vision/upload with multipart/form-data

4. Display Result

• Show the AI's analysis/description
• Show token usage and credits consumed

Credit Consumption

Vision uses post-deduct billing: 2 base credits + token-based cost (calculated from prompt_tokens and completion_tokens).

Example Conversation

User: /vision -i ./screenshot.png -p "What errors are shown in this screenshot?"

You:

1. Parse arguments - local file, prompt about errors
2. Check user has minimum balance
3. Upload file via /api/v1/ai/vision/upload
4. Display AI analysis and credits consumed

User: /vision --image "https://example.com/chart.png" --prompt "Summarize the data in this chart"

You:

1. Parse arguments - remote URL, prompt about chart data
2. Check user has minimum balance
3. Send URL via /api/v1/ai/vision
4. Display AI analysis and credits consumed

User: /vision -i ./product.jpg -p "Write an e-commerce product description for this item"

You:

1. Parse arguments - local product image
2. Check user credits
3. Upload and analyze via /api/v1/ai/vision/upload
4. Display generated product description

Notes

• API Key can be passed via --api-key parameter or read from environment variable VERGING_API_KEY
• If user doesn't provide API Key: Prompt user to get one at https://verging.ai
• For local files, the image is uploaded to R2 storage first, then analyzed
• For URLs, the image URL is passed directly to the vision model
• Maximum image file size: 20 MB
• Post-deduct billing: credits are deducted after the response is generated

Privacy and Security

API Key

This skill requires a verging.ai API Key. Get it from:

1. Visit https://verging.ai

3. Create a new API key

Security recommendations:

• Never expose your API key in public repositories
• Set it via environment variable: export VERGING_API_KEY="your_key"

Data Handling

• Images are sent to the vision model for analysis
• Uploaded images are stored temporarily on R2 CDN
• No image data is retained beyond the session
