Unlock Protocol
Unlock Protocol is an open-source, community-governed protocol for onchain memberships and subscriptions. Creators deploy "locks" (membership smart contracts) that mint time-based, optionally recurring membership NFTs ("keys") across Ethereum, Base, Optimism, Polygon, Arbitrum, and other networks. The hosted Locksmith REST API adds off-chain conveniences — metadata storage, event ticketing with QR verification, checkout configuration, receipts, fiat payments via Stripe Connect, WebSub webhooks, and email delivery — while GraphQL subgraphs index the contracts per network. Originally built by Unlock Labs, stewardship passed to the Unlock Protocol Foundation and the Unlock DAO in 2025.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Unlock Protocol the way a machine reads it — 38 machine-readable artifacts across 34 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 — Unlock Protocol scores 52.4/100 (developing), with a separate agent-readiness read of 57/100 (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.

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 Unlock Protocol
Each block below is one kind of artifact we hold for Unlock Protocol. 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 34
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.

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.
