Payment Flow

1. AI agent calls an MCP tool（e.g. asia_intelligence）
2. MCP Server POSTs to Hermes Worker → receives HTTP 402
3. MCP Server parses WWW-Authenticate header（x402 v2 manifest）
4. MCP Server signs manifest with wallet private key（EIP-191）
5. MCP Server retries with Authorization header
6. Worker returns data; USDC transferred on-chain atomically

No API keys. No subscriptions. Pay per call.
