# Prompt: `agent-card.json` (A2A protocol)

**File:** `/.well-known/agent-card.json` · **Status:** 🚀 New, enterprise-led, 150+ companies adopted in 2025 · **Time to ship:** 30 min (if your agent already exists)

A JSON "business card" for an AI agent hosted at your domain. Part of Google's Agent2Agent (A2A) protocol, now governed by the Linux Foundation. Used so other agents can discover what your agent can do.

**Skip this unless you're running an agent.** This file is only relevant if you're _operating_ an AI agent (not just running a website). If you're building a customer-service agent, scheduling agent, or internal tool that should be callable by other AI systems (Salesforce, ServiceNow, SAP, and PayPal are all on A2A), this is how they find you. Most small sites can skip.
