Wisely x402 Agent-Payment Infrastructure

This connects Claude to Wisely's x402 payment infrastructure for agent-initiated transactions. The server exposes rails for checking payment status, quoting costs before execution, generating receipts, and handling wallet signing flows. You'd reach for this when building agents that need to pay for hosted API endpoints or services directly, with built-in proof and receipt tracking. The workflow is quote first, get user approval for signing, then execute with streamed progress for long-running calls. It includes developer credits for testing and supports both internal Wisely services and external x402 sellers through a standardized rail protocol.
