Housing Data Toolkit
The older toolkit embedded legacy X-PAYMENT/X-PAYMENT-TX instructions. Those are retired from current buyer authority.
Discover current housing/data capabilities through https://mcp-x402.onrender.com/mcp or the live SqueezeOS contracts.
When a target requires payment, read its fresh PAYMENT-REQUIRED challenge and use caller-controlled PAYMENT-SIGNATURE authorization only if policy accepts the exact terms.
