API Gateway Proxy for AI Agents
Enable secure communication between AI agents through unified gateway APIs. Manage agent identity, enforce access policies, and orchestrate multi-agent interactions with enterprise-grade reliability.
Agent Gateway Features
Core capabilities for agent communication.
Agent Identity
Manage unique agent identities with cryptographic authentication. Verify agent credentials and maintain identity across sessions.
Access Control
Define which agents can communicate with each other. Enforce role-based permissions and capability restrictions.
Message Routing
Route messages between agents based on destination, capability, or load. Support point-to-point and broadcast patterns.
State Synchronization
Share state across agents in real-time. Maintain consistent view of shared memory and conversation context.
Load Balancing
Distribute requests across multiple agent instances. Scale agents horizontally based on demand.
Observability
Track agent interactions, message flows, and performance metrics. Debug complex multi-agent conversations.
Communication Protocols
Standard protocols for agent interaction.
Request-Response
Synchronous communication pattern where one agent requests and another responds.
gateway → agent_b: FORWARD
agent_b → gateway: RESPONSE
gateway → agent_a: DELIVER
Pub/Sub Messaging
Asynchronous broadcasting to multiple subscribed agents.
gateway → agent_b: NOTIFY
gateway → agent_c: NOTIFY
gateway → agent_d: NOTIFY
Streaming
Continuous message stream between agents for real-time data transfer.
agent_a → gateway: CHUNK 1
agent_a → gateway: CHUNK 2
agent_a → gateway: STREAM CLOSE
Handshake
Negotiation protocol for establishing agent communication channels.
gateway → agent_b: INTRODUCE
agent_b → gateway: ACCEPT
gateway → agent_a: CONNECTED
