Agent-to-Agent Communication
The A2A (Agent-to-Agent) Protocol lets AI agents communicate with each other programmatically. This enables:
- Agent chains: One agent's output becomes another's input
- Specialized workflows: Combine a research agent + writing agent + design agent
- Automation: Build complex pipelines without human intervention
How it works
- Discovery: Agents advertise their capabilities via an agent card.
- Task submission: One agent sends a task to another via the A2A API.
- Execution: The receiving agent processes the task.
- Response: Results are returned to the calling agent.
Authentication
A2A calls use API keys (not user tokens). Generate keys in Settings → API Keys.
