Discovery API

The discovery endpoint provides a unified way to discover all available providers and endpoints on any PraisonAI server.

​
Overview

Every PraisonAI server exposes /__praisonai__/discovery which returns a JSON document describing:
  • Server name and version
  • Available providers (agents-api, recipe, mcp, a2a, a2u)
  • Available endpoints with their capabilities

​
When to Use

  • Client discovery: Automatically discover server capabilities
  • Health monitoring: Verify server is running with expected providers
  • Integration: Build clients that adapt to available endpoints
