Media Chain
Mediachain (Mediachain Labs) was a decentralized universal media library and attribution protocol built on IPFS and blockchain technology, designed to let creators and applications collaborate on open metadata about creative works and track the provenance and ownership of online images and other media. Founded in 2016 with seed funding from Andreessen Horowitz and Union Square Ventures, the company was acqui-hired by Spotify in April 2017 to help build fair, blockchain-based royalty attribution for rightsholders. The company is now defunct and its primary domain (mediachain.io) is a parked page, but its open-source protocol, design documentation, Protocol Buffer definitions, and first-party client libraries (the `aleph`/`mcclient` JavaScript client on npm and the `mediachain-client` Python reader on PyPI) remain public under the github.com/mediachain organization. This profile was surfaced as an a16z portfolio company and enriched from its surviving open-source surface.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
Media Chain 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 — Media Chain scores 16.8/100 (emerging), with a separate agent-readiness read of 13/100 (agent aware). 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

Put this on your own site. The badge is drawn live from Media Chain's current Kin Score — paste it once and it updates itself every time the score is recomputed. It follows your visitor's light or dark setting, and it links back here so anyone who sees it can read the full breakdown.

Media Chain 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.

This is an independent, third-party profile of Media Chain, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
