Mux
Mux is a video infrastructure platform that gives developers an end-to-end API for ingesting, encoding, storing, delivering, and analyzing video. The platform spans Mux Video (on-demand and live streaming), Mux Data (quality-of-experience analytics), Mux Robots (AI workflows for captions, chapters, summarization, and moderation), and Mux Player (drop-in playback components). Mux exposes a unified REST API at api.mux.com plus delivery hosts at stream.mux.com, image.mux.com, and stats.mux.com, backed by official SDKs in Node, Python, Ruby, PHP, Go, and Elixir, a CLI, and player integrations across web, iOS, Android, Roku, and major HTML5 players.
Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.
API Evangelist profiles Mux the way a machine reads it — 115 machine-readable artifacts across 36 APIs, 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 — Mux scores 77.0/100 (exemplar), with a separate agent-readiness read of 48/100 (agent ready). 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 Mux
Each block below is one kind of artifact we hold for Mux. 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 36
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.
