Three endpoints. One proof your users and their customers can check themselves.
Claim
Register one image per call with an exact SHA-256 and a perceptual fingerprint.
Bulk claim
Register up to 20 images per request — idempotent, so retries are safe.
Verify
Public lookup finds exact matches and modified copies. No key required.
Bitcoin anchoring
Every claim is timestamped via OpenTimestamps and confirmed on Bitcoin.
Branded certificates
Each claim gets a public certificate carrying your logo and brand color.
Private by design
You send fingerprints, never pictures. We cannot see your images.
You can't stop the fakes. You can prove what's real.
A StillMine certificate proves an exact file existed and was claimed under a name at a recorded time — verified by mathematics, not by us. It does not detect deepfakes or settle copyright on its own; it gives your users an honest, checkable record of origin.
