Recent events

  • Google publishes the AP2 specification in an open GitHub repo

    The google-agentic-commerce/AP2 repository publishes the Agent Payments Protocol specification, including agent authorization. This is maintainer evidence of an implementation surface distinct from x402 HTTP headers.

  • Google announces the Agent Payments Protocol (AP2)

    On 16 September 2025 Google Cloud announced AP2, an open protocol developed with payments and technology firms so agents can initiate payments across methods. Google positions AP2 as usable as an extension of A2A and MCP, and as payment-agnostic rather than a stablecoin-only HTTP 402 overlay.

  • Trade press same-day coverage of AP2 is corroboration, not a primary source

    TechCrunch reported Google’s AP2 launch on 16 September 2025, describing backing from merchants and financial institutions. zFinia treats this as TIER_C corroboration of an already TIER_A official announcement.
