What is npayload?
The communication infrastructure for autonomous systems, explained in two minutes
The one-line answer
npayload is the communication infrastructure for autonomous systems.
AI agents, microservices, serverless functions, autonomous pipelines: any system that needs to communicate reliably with other systems, internally or externally, uses npayload. It handles the hard parts that every team rebuilds from scratch:
- Send messages to other agents or services, internally and externally
- Receive messages with guaranteed delivery and automatic retries
- Trust the systems you communicate with (OAuth 2.0 + DPoP, encryption)
- Prove what was said, when, and to whom (immutable audit trail)
One API. Any language. Any cloud.
The problem
Autonomous systems are multiplying. Every company is building AI agents, automated pipelines, and interconnected services. But there is no standard infrastructure for their communication:
- No reliability. HTTP calls fail silently. No retries, no dead letter queues, no delivery guarantees.
- No trust. How does System A know System B is who it claims to be? How do they negotiate terms?
- No audit trail. When an autonomous system makes a critical decision, who can prove what happened?
- No isolation. Data from one customer leaks into another. No encryption. No data residency.
- External communication is painful. Setting up reliable webhooks, retry logic, signature verification, and circuit breakers for every integration takes weeks. npayload gives you all of it out of the box.
npayload solves all of this with a purpose-built communication infrastructure.
How it fits
npayload works with your existing stack, not against it. It provides adapters for Kafka, SQS, EventBridge, SNS, Azure Service Bus, GCP Pub/Sub, and more.
Key concepts
| Concept | What it is |
|---|---|
| Channel | A named message stream. Publish to it, subscribe to it. |
| Message | A JSON payload published to a channel. Immutable once stored. |
| Subscription | A webhook or queue that receives messages from a channel. |
| Delivery | The act of sending a message to a subscriber. Tracked, retried, guaranteed. |
| Instance | An isolated deployment, dedicated or shared. Your data stays in the instance you are assigned to. |
| ASP | Agent Session Protocol for sessions, trust scoring, and negotiation between agents. |
