The Universal Invocation Layer for AI Agents

One API to run them all. Invoke agents built on any framework: Agno, Strands, LangGraph, or custom implementations, with native support for Streaming (SSE), Sync, and Async execution.

bash
# Invoke an agent with real-time event streaming
$
curl -X POST 'https://api.xpander.ai/v1/agents/{agent_id}/invoke/stream' \
-H 'x-api-key: YOUR_API_KEY' \

-d '{

"text": "Analyze these documents",
"files": ["https://example.com/report.pdf"]
},
"events_streaming": true
}'

Framework Agnostic

Bring your own agent. Whether you build with Agno, Strands, LangGraph, or custom implementations, wrap them in one standardized API specifically designed for agentic workflows.

Real-Time Streaming (SSE)

Stream responses instantly. Native Server-Sent Events (SSE) support lets you stream thoughts, intermediate steps, and final answers to your UI without latency.

Enterprise Control

Built for scale. Invoked agents run as serverless agents in the cloud, or in your own Kubernetes cluster. Includes managed authentication, PII masking, and audit logs.

How it Works

Pass rich context, user details, and file attachments effortlessly with a simple JSON payload.

payload.json
{
"input": {
"text": "Extract insights from feedback"
},
"output_format": "json",
"output_schema": {
"type": "object",
"properties": {// Define schema...}
},
"events_streaming": true
}

Use Cases

Unified Agent Governance

Stop fragmentation. Your data science team uses LangGraph; your engineering team uses AutoGen. The Agents API standardizes the invocation contract across your entire organization.

Powering Custom Experiences

Build AI Assistants, enterprise search systems, or chat interfaces by simply hitting a standard REST endpoint. With native SSE streaming, you can deliver 'Copilot-like' experiences.

Complex Orchestration

Move beyond simple chatbots. Use the API to trigger chain-reactions where one agent's output becomes another's input. Orchestrate multi-step workflows with full visibility.
