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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Everledger the way a machine reads it — 5 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Everledger scores 35.7/100 (thin), with a separate agent-readiness read of 14/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Everledger
Each block below is one kind of artifact we hold for Everledger. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 1
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Everledger Platform API (Amplify)
The Everledger Platform API — marketed as Amplify — is a suite of REST APIs that let organizations access and embed blockchain-backed provenance data in their own systems. Core ...
Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Everledger Plans
PLANSRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
