Skyfire

Skyfire is the open identity and payments layer for AI agents. It lets AI agents securely create accounts, verify a real-world identity (Know Your Agent, KYA), and autonomously pay for digital services using token-based authentication and stablecoin settlement. Developers use Skyfire to monetize APIs, tools, MCP servers, and content directly to agents. The platform issues three signed, interoperable KYAPay token types — kya (identity), pay (payment), and kya-pay (combined) — that buyer agents present to seller services over a simple REST API and a hosted MCP server. Sellers validate and charge tokens, discover services, and manage seller-service lifecycles, while enterprises manage users and agents through admin APIs. Skyfire is backed by DCVC, Lightspeed Venture Partners, and Trinity Ventures.

agent aware

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Skyfire 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 — Skyfire scores 36.1/100 (thin), with a separate agent-readiness read of 38/100 (agent aware). 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 Skyfire

Each block below is one kind of artifact we hold for Skyfire. 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.

Skyfire API

REST API for AI-agent identity and payments. Buyer agents create kya, pay, and kya-pay tokens; seller agents introspect and charge tokens and manage seller services; enterprises...

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.

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.
