How this service works
Verify that an image matches a reference image. Compares a candidate image URL against a trusted reference and returns whether they show the same content. Use for verifying logos, profile pictures, KYC document photos, or that an uploaded image matches an expected original.
Output
A boolean or decision indicating whether the two images match (i.e., show the same content), along with any confidence or similarity details the service returns.
Example use cases
KYC document photo verification
“I need to verify that the ID photo a user uploaded at https://uploads.example.com/user456/id.jpg actually matches the reference document photo we have on file at https://kyc.example.com/reference/user456.jpg — can you check if they show the same person?”
Logo upload compliance check
“Before we publish this partner's logo submission at https://submissions.example.com/partner99/logo.png, can you confirm it matches our approved reference logo at https://brand.example.com/official-logo.png?”
Detecting swapped product images
“Someone may have replaced our product image — can you verify that https://store.example.com/product42/main.jpg still matches the original approved photo at https://assets.example.com/products/42-original.jpg?”
Technical details
Endpoint
POSThttps://api.kakerapetit.dev/v1/verify-reference-imageWhen to prefer
Choose this endpoint when you need a binary verification decision — does image A match image B — rather than a raw similarity score. It is well-suited for compliance, KYC, brand validation, and identity workflows where you need a pass/fail answer on whether two images represent the same content.
Side effects
- Invalid or inaccessible image URL (non-HTTPS, 404, or auth-required) returns an error
- Image exceeds 10MB size limit causing rejection
- Unsupported image format (non-JPEG/PNG/WebP/GIF) returns an error
- Network timeout fetching one or both remote images
- Ambiguous or borderline matches may return uncertain results
