Phantom
Phantom is a self-custodial multi-chain crypto wallet for Solana, Ethereum, Polygon, Base, Bitcoin, Sui, Monad, and HyperEVM, distributed as a mobile app (iOS/Android) and browser extension with more than 20 million users. For developers, Phantom exposes injected Provider APIs per chain on window.phantom (Solana, EVM, Bitcoin, Sui) following the Wallet Standard and EIP-1193, a Universal Link / phantom:// Deeplinks API for mobile dApp integration with encrypted session handshakes, a multi-platform Connect SDK suite (React, React Native, Browser SDKs) with embedded wallet support and OAuth social login (Google, Apple), and a Phantom MCP Server that exposes 27 tools across wallet operations, swaps, portfolio rebalancing, and Hyperliquid perpetuals for AI agents — each agent receives its own wallet via device-code authentication. Apps register through the Phantom Portal to obtain an App ID, configure redirect URLs, verify domains, and opt into auto-confirm contracts.
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 Phantom the way a machine reads it — 12 machine-readable artifacts across 10 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 — Phantom scores 29.4/100 (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 Phantom
Each block below is one kind of artifact we hold for Phantom. 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 10
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.

Security 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.
