Agent-to-Agent Setup

When wanting to connect Agents (allowing one agent to call another agent) we use our Functions Skill.

We provide a general Webhook that can be used if you pass the specific Agent API Key you want to call with the function.

The first step is to setup a Function under the Agent (function skill)

The Function Skill will pass the query to the other Agent for a response and include back into the conversation. To Setup: Provide Function instructions on when the Agent should call the other agent (essentially added to the core prompt for the AI to look for this prompt to trigger the function) Webhook

To use our generic A2A Webhook - use this URL:

Provide Function Parameters (which for this use case we just need to pass the question the user prompted into the agent

Function Instructions:

{
  "type": "object",
  "required": [
    "query"
  ],
  "properties": {
    "query": {
      "type": "string"
    }
  }
}

Header Variable

Next, add a Header Variable using the following: Header Name = Call_Agent_APIKEY

Header Value = { API Key of the Agent you want to call }
