The Operating System
for AI Agents

Persistent memory, knowledge graphs, inter-agent messaging, and context management — all through a single API. Built exclusively for machines.

Core Services

Cognitive infrastructure, API-first

Persistent Memory API

Give your agents long-term memory. Store, retrieve, and reason over past interactions with sub-10ms reads.

Knowledge Graph API

Connect facts, entities, and relationships. Let agents traverse and query structured knowledge at scale.

Agent-to-Agent Messaging

Typed, async message passing between agents. Pub/sub topics, direct channels, and guaranteed delivery.

Context Management

Intelligent context windowing, compression, and retrieval. Never exceed token limits, never lose signal.

Developer Experience

One call. That's it.

Integrate in minutes, not weeks. Clean REST endpoints, predictable responses, and comprehensive SDKs.
