Pex

Pex (part of Vobile since April 2025) is a content-identification and digital-rights technology company whose APIs identify recordings, compositions, and AI-generated music across digital platforms. Pex operates three developer-facing APIs: a Discovery / DRM & CMS API (api.pex.com) for managing rights assets, monitoring infringing copies, and running takedowns; a real-time Search API for automatic content recognition (ACR) that fingerprints and matches audio even when it has been sped up, slowed down, pitch-shifted, or partially obscured against a registry of 120M+ indexed recordings; and an AI Song Detector API (api.ae.pex.com) that classifies whether a track was generated by an AI music model such as Suno, Udio, Boomy, or ElevenLabs. Pex also publishes a hosted MCP server (mcp.pex.com) exposing the AI Song Detector to agents. Customers include streaming platforms, distributors, publishers, production-music libraries, and collection societies.

agent aware

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Pex the way a machine reads it — 6 machine-readable artifacts across 3 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 — Pex scores 32.3/100 (thin), with a separate agent-readiness read of 38/100 (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.

How we profile Pex

Each block below is one kind of artifact we hold for Pex. 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 3

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.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Security 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.
