Its public Agent Hub API exposes 34 free REST operations (OpenAPI 3.1) that read those contracts and return unsigned transactions for the caller to sign, plus 77 x402-priced endpoints paid per call in USDC, an 18-skill A2A agent card, llms.txt, agents.txt, a published Agent Skill and a stdio MCP server on npm.
