Keygen

Keygen is a software licensing, entitlements, and distribution API for desktop, on-prem, IoT, and other installed applications. It issues license keys, activates and tracks machines, enforces policy-based entitlements, and distributes releases and artifacts for auto-updates. Keygen ships as the source-available, self-hostable Keygen CE / EE and as the managed Keygen Cloud, exposing a JSON:API interface under api.keygen.sh.

agent ready

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 Keygen the way a machine reads it — 21 machine-readable artifacts across 12 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 — Keygen scores 41.9/100 (thin), 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 Keygen

Each block below is one kind of artifact we hold for Keygen. 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 12

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.

Keygen Artifacts API

Binary artifacts attached to releases.

Keygen Components API

Hardware components of a machine fingerprint.

Keygen Entitlements API

Named feature flags attached to policies and licenses.

Keygen Licenses API

Issue, validate, and manage license keys.

Keygen Machines API

Activate and manage node-locked machines.

Keygen Policies API

Licensing rules that govern licenses.

Keygen Processes API

Concurrent processes running on a machine.

Keygen Products API

Applications being licensed and distributed.

Keygen Releases API

Distributable, semver-tagged releases.

Keygen Tokens API

Authenticate and manage bearer tokens.

Keygen Users API

End users and license owners.

Keygen Webhooks API

Webhook endpoints and events.

Open Collections 1

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

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.

Rate 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.

Keygen Rate Limits

4 limits

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Security Posture 4

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.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
