A2A Transport

A2A (Google Agent-to-Agent) enables multi-agent coordination. Agents can expose themselves as A2A agents.

Mapping

A2A Concept	OAP Mapping
Agent Card	Agent descriptor

Message	Event or Command

Transport Configuration

"a2a": {
  "agent_card_url": "https://your.compliant.oap.endpoint/.well-known/agent.json"
}

A2A transport is optional — REST is the baseline. A2A is declared in the /.well-known/oap manifest only if the endpoint supports it.
