Everledger

Everledger is a supply-chain transparency company that uses a private, enterprise blockchain plus IoT to create tamper-evident digital identities ("digital twins") for physical assets and to track their provenance from origin to market. Its platform spans diamonds, coloured gemstones, wine and spirits, art, fashion and luxury goods, critical minerals, batteries and insurance. The developer surface is the Everledger Platform API (marketed as "Amplify") — a suite of REST APIs including the Provenance API (a full, media-rich provenance report for any object), the Object API (verify an object's identity against its digital twin) and the Transfer API (reassign ownership of a digital asset on the blockchain when a sale is made) — plus an embeddable Amplify Widget for eCommerce. Access is via the invite-only Everledger Developer Community (EDC). Founded by Leanne Kemp and backed by Bloomberg Beta, the company restructured in 2023 and continues to operate on its core gems, minerals and textiles markets.

Everledger publishes 1 API on the APIs.io network. Tagged areas include Company, Blockchain, Provenance, Supply Chain, and Traceability.

Everledger’s developer surface includes documentation, pricing, support, signup flow, changelog, and 13 more developer resources.
