Derivation Chain

Step 1 Proliferation of AI image generation models such as Google Nano Banana 2

Step 2 Growing demand for AI-generated image detection
→
Step 3 Specialized watermark detection API for AI image detection service customers

Problem

With the rapid proliferation of AI image generation models, news media outlets, academic publishers, and E-commerce Platform operators (3–50 employees) need to determine whether uploaded images are AI-generated. However, each model (Midjourney, DALL-E, Stable Diffusion, Nano Banana, etc.) embeds watermarks differently, making unified detection with a single tool impossible. Manual verification takes 5–15 minutes per image, and platforms processing 100+ images daily must hire a dedicated staff member at approximately $2,250/month.

Solution

An API service that provides unified watermark detection across multiple AI image generation models. Core features: (1) Automatic detection of watermarks/metadata from 10+ models including Nano Banana, Midjourney, DALL-E, and SD upon image upload, (2) JSON API response with detection results (model name, confidence score, watermark type), (3) Bulk batch processing and webhook callback support. Multi-model unified detection with an API-first design is the key differentiator.

Target: News media (editorial departments), academic publishers, E-commerce Platform operations teams, 3–50 employees, ages 25–45
Revenue Model: API usage-based pricing at $0.04 Per Transaction (up to 10K/month), $0.02 per call beyond 10K. Monthly Subscription: $37/month (10K calls included). Enterprise: $217/month (100K calls included).
