Front matter through Chapter 5
Conceptual framing and participant taxonomy are stable for launch; agent-to-agent share now adds live market-shape evidence.
Edition Verification Passport
The x402 Handbook, with live evidence attached.
This passport ties the launched Kindle edition to current protocol evidence, paid endpoint samples, market telemetry, and companion projects. It is the living layer beside the book, not a replacement for the book.

What This Verifies
The book is tied to a set of public companion resources that can age independently from the published prose. The goal is to make drift visible: if x402 headers, facilitator behavior, buyer-agent patterns, or market evidence change, readers can see the current evidence here.
This page does not make legal, tax, investment, or financial claims. It tracks evidence freshness and companion links for a fast-moving payments protocol.

Chapter Currency
Chapters 6-7
Buyer and seller examples should be checked against current V2 headers and the public temperature-server companion.
Chapters 8-14
Trust Index, Directory, Sample Outputs, Bazaar sweeps, and Agent-to-Agent Share supply current market evidence.
Chapter 15
The x402 temperature station remains the public hands-on companion; paid-route behavior and health checks are monitored separately.
Chapter 16
Enterprise agent-commerce framing is stable, but governance, identity, and platform controls are moving quickly.
Chapters 17-19
Risk, safety, and future-facing claims track paid failures, blocked providers, identity work, and agent-to-agent money flow.
