Technical details
Endpoint
POSThttps://api.kakerapetit.dev/v1/check-duplicate-imageWhen to prefer
Use this endpoint when you need to programmatically compare two specific images by URL to determine if they are duplicates — ideal for deduplication pipelines, content moderation workflows, or verifying that an uploaded image does not already exist in a dataset. Suitable for single pair-wise comparison at low cost.

- Unsupported image format (not jpeg, png, webp, or gif)

- Either image_url_a or image_url_b is missing from request body
- Network timeout fetching remote image
