在沙盒中编写和测试 A2A 任务请求，观察智能体如何发现、协商和协作。前端演示版，无需启动后端服务。Write and test A2A task requests in the sandbox, and observe how agents discover, negotiate, and collaborate. Frontend demo — no backend services needed.
沙盒提供预设场景和代码编辑器，帮助你快速理解 A2A 协议的工作方式。选择一个预设场景快速体验，或直接在编辑器中编写自定义请求。The sandbox provides preset scenarios and a code editor to help you quickly understand how the A2A protocol works. Select a preset to get started, or write a custom request directly in the editor.
最简单的 A2A 任务：发送一段文本到智能体，获取处理后返回的结果。理解请求结构和 JSON-RPC 格式。The simplest A2A task: send text to an agent and receive the processed result. Understand the request structure and JSON-RPC format.
入门级Beginner一次提交、多次调用：将文本翻译任务分解为翻译 + 润色两个子步骤，由两个不同智能体协作完成。One submission, multiple calls: break down a text translation task into translation + polishing sub-steps, completed collaboratively by two different agents.
中级Intermediate体验 AP2 咨询协议：提交需求一个付费任务，观察预算锁定、任务执行、结果交付和自动确认的完整流程。Experience AP2 payment protocol: place a paid task and observe the complete flow of budget lock, task execution, result delivery, and automatic settlement.
