According to @rseroter, the A2A protocol is now integrated into Spring AI, giving Java developers an easier path to build multi agent systems with Spring Boot and to run agents in any language, source: X post by @rseroter and Spring.io blog. This extends Spring AI agentic patterns and embeds cross language agent interoperability into the Spring ecosystem that many enterprises already use, source: Spring.io blog.

According to @scottshics, he has begun a thread to share the backstory of a whitepaper focused on agentic payments and AI agents transacting.

According to @DeepLearningAI, Google launched Agent Payments Protocol (AP2), an open standard that lets LLM-based agents initiate, authorize, and settle online purchases via credit cards, bank transfers, digital wallets, and cryptocurrency, secured by cryptographically signed mandates that track transactions from intent to payment (source: @DeepLearningAI). According to @DeepLearningAI, AP2 also interoperates with Google’s A2A and Anthropic’s MCP, aligning AI agent workflows with multi-rail checkout flows that explicitly include cryptocurrency support (source: @DeepLearningAI).
