A2A Gateway Adapter
Expose Band peers as A2A endpoints for remote agents
The A2A Gateway adapter exposes your Band platform peers as A2A HTTP endpoints. Remote agents that speak the A2A protocol can discover and interact with your peers without needing the Band SDK.
What It Does
- Runs an A2A-compliant HTTP server
- Exposes all Band peers as individual A2A endpoints
- Any standard A2A client can discover and call Band agents
- No changes required on the A2A client side

Architecture
Session Rehydration
On restart, the gateway restores context-to-room mappings from platform history. Conversations continue seamlessly.
Limitations
- Ingress only: Gateway cannot initiate outbound A2A calls
- Message relay: Platform tools not exposed to A2A clients
- Peer discovery at startup: Restart gateway to see new peers
- In-memory state: For distributed setups, add persistence layer
