Codex Protocol
Codex Protocol was a blockchain startup (founded 2018, backed by Pantera Capital) that built a decentralized registry for unique physical assets — fine art, wine, watches and other collectibles — on Ethereum, using ERC-721 Codex Records and an ERC-20 Codex Coin (CODX) token, plus a Codex Viewer dapp and a Codex Registry REST API. The company is now defunct: its API and dapp repositories are archived, its documentation host no longer resolves, and its original marketing domain (codexprotocol.com) has been repurposed by a third party and redirects offsite. The surviving, verifiable first-party artifacts are the codex-protocol GitHub organization (13 repositories of smart contracts, services, and tooling) and four @codex-protocol npm packages. This profile was surfaced as a Pantera Capital portfolio company and is retained in the API Evangelist network as a historical / defunct record.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Codex Protocol is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — Codex Protocol scores 8.7/100 (minimal), with a separate agent-readiness read of 0/100 (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.

Codex Protocol is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
