Bitcoin
Bitcoin is the original decentralized peer-to-peer digital currency and open-source protocol, first described in the 2008 whitepaper by Satoshi Nakamoto. It is not a company or a hosted commercial API; the reference implementation, Bitcoin Core, exposes a local JSON-RPC interface for node operators and application developers to query the blockchain, manage wallets, build and broadcast transactions, and interact with the peer-to-peer network. bitcoin.org and the developer documentation site at developer.bitcoin.org publish developer guides, an extensive RPC API command reference, worked examples, and reference material for building Bitcoin applications. This profile was seeded as a Ribbit Capital portfolio-sector lead and enriched from Bitcoin's public developer surface.
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 Bitcoin 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 — Bitcoin scores 12.7/100 (minimal), with a separate agent-readiness read of 7/100 (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 Bitcoin
Each block below is one kind of artifact we hold for Bitcoin. 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.
