Keybase
Keybase is an end-to-end encrypted messaging, file-sharing, and key-directory platform built on public-key cryptography, founded by Chris Coyne and Max Krohn and acquired by Zoom in 2020. It maps human-readable usernames to public keys and cryptographically verifiable social-identity proofs (Twitter, GitHub, Reddit, Hacker News, personal domains, and cryptocurrency addresses), and provides encrypted chat, teams, KBFS encrypted filesystem, git, and a wallet. Keybase exposes a public read-oriented HTTP JSON API (version 1.0) at keybase.io/_/api/1.0 for user lookup, PGP key fetch, Merkle-tree verification, and session/signature auth, plus officially supported chat-bot SDKs for Node.js, Python, and Go that script the local keybase client and CLI.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Keybase the way a machine reads it — 4 machine-readable artifacts across 1 API, 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 — Keybase scores 20.0/100 (emerging), 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 Keybase
Each block below is one kind of artifact we hold for Keybase. 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 1
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.

MCP SERVERSecurity 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.
