# AsyncAPI Specification

**Canonical:** https://apis.io/apis/agent-readiness/asyncapi-initiative/  
**Provider:** Agent Readiness — https://apis.io/providers/agent-readiness/  
**Base URL:** https://www.asyncapi.com  
**Documentation:** https://www.asyncapi.com

AsyncAPI Specification is one of 15 APIs that [Agent Readiness](https://apis.io/providers/agent-readiness/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Event-Driven APIs, Agent Readiness, Async, and Standards. The published artifact set on APIs.io includes API documentation and a GitHub repository.

Machine-readable contract for event-driven APIs (webhooks, message brokers, streaming). Agent-readiness for event surfaces depends on whether the provider ships an AsyncAPI document so agents can subscribe, dispatch, and validate events programmatically.
