The A2A Protocol: Standardizing the /run Endpoint for Cross-Platform Agent Discovery

In a world where thousands of developers are building specialized AI agents, we face a critical challenge that mirrors the early days of the web: a lack of standardization. If every agent exposes its capabilities through a custom API with unique endpoints (`/execute`, `/invokeTask`, `/process`), we create a digital 'Tower of Babel.' This forces an 'N x M' integration nightmare, where every one of N consuming agents must write custom, brittle code to interact with M different agent providers.

The A2A x402 Extension: Enabling Production-Ready Agent-Based Crypto Payments

As the AI agent ecosystem matures, a new economic model is required. A powerful data analysis agent may need to call a specialized, third-party sentiment analysis tool on a per-use basis. A research agent might need to pay a few cents to access a premium, paywalled academic paper. Traditional payment methods—monthly subscriptions, credit card forms, and user-based accounts—are far too slow, heavyweight, and human-centric for a world of high-speed, autonomous, machine-to-machine interactions.

Beyond Monoliths: Crafting Interoperable AI Systems with Google’s A2A Agent Architecture

In today’s interconnected digital landscape, building intelligent systems often means orchestrating multiple specialized services. Google’s Agent-to-Agent (A2A) protocol provides an elegant and standardized way for these services — or “agents” — to discover, interact, and collaborate. This document provides a technical deep dive into a generic A2A architecture and its components.

Securing A2A Endpoints with OAuth 2.0 and Scoped Permissions

In a burgeoning Agent-to-Agent (A2A) ecosystem, AI agents are constantly discovering and invoking each other's services. An ImageResizeAgent exposes an endpoint, and a ReportGeneratorAgent wants to use it. But how does the ImageResizeAgent (the Resource Server) know that the incoming request is legitimate and authorized? Simply relying on static API keys is a dangerous anachronism. API keys are binary (all or nothing), offer no granular control, and if compromised, grant unlimited access to a resource.
