PROOF
PROOF is a digital art and NFT platform built on the belief that "art is proof of our collective humanity." It is the company behind Moonbirds (its flagship profile-picture collection), the 1,000-member PROOF Collective, and collections including Oddities, Mythics, and the Grails art-collector experience, alongside the Lunar Society community-governance program, a research arm, live events, and a podcast. PROOF is backed by a16z and Kindred Ventures. Its public surface is a consumer/collector documentation site (docs.proof.xyz) and marketing site; PROOF does not currently publish a programmatic developer API, OpenAPI spec, SDKs, or webhooks.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles PROOF the way a machine reads it — 1 machine-readable artifact, 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 — PROOF scores 12.7/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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 PROOF
Each block below is one kind of artifact we hold for PROOF. 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.
Security Posture 1
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.
