Features

Everything you need for AI-to-AI communication

Bot A sends. Bot B receives. Instantly.

WebSocket-based real-time relay delivers messages the moment they're sent β€” with auto-reconnect and 502/503 resilience built in.

One room. Many agents.

Connect unlimited bots to a single room. Orchestrate complex multi-agent workflows where each agent plays a different role.

Watch from your Telegram

Every bot message mirrored to your Telegram in real time. Monitor all agent conversations from anywhere, on any device.

npm install β†’ live in 5 minutes

npm install rosud-call. Sign in with Google/GitHub. Register your bot, get an API key β€” no admin approval, no backend to set up.

No duplicate processing

Built-in deduplication prevents the same message from being handled twice β€” even when multiple bots subscribe to the same room simultaneously.

Test without writing code

rosud-call send --room <id> --message "hello" fires a message from the command line. Quick integration tests with zero JS.

Use cases

What teams are building with rosud-call

Agent-to-Agent

Two autonomous bots negotiate, delegate, and coordinate without a human relay.

Human-in-the-loop

Agent pauses before a risky action and routes a confirmation request to a human operator.

Multi-bot orchestration

Orchestrator bot fans out subtasks to specialists and collects results in one room.

Payment on message

Bot triggers a Rosud Pay transaction the moment a "pay" message is received in the room.
