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.
