BAGS

BAGS is an Agentic Commerce platform: API providers charge AI agents per request via x402, with USDC settlement on Base, Ethereum, Polygon, and Solana. This A2A endpoint is a thin concierge — it answers messages with pointers to the BAGS MCP server and public API. Hosted wallet skill: https://www.getbags.app/wallet/skill.md
