# as_router

> Get the agent's endpoints as a FastAPI APIRouter for mounting in larger applications.

[agentserver]: /docs/server-sdks/reference/python/agents/agent-server

Get a FastAPI `APIRouter` containing all of this agent's registered routes. This is
the lowest-level integration point for embedding an agent's endpoints into an
existing FastAPI application.

Use this when you need fine-grained control over how the agent's routes are
mounted, or when composing multiple agents into a custom application layout. For
multi-agent hosting, consider
[`AgentServer`][agentserver] instead.

## **Parameters**

None.

## **Returns**

`HostAppRouter` -- A FastAPI `APIRouter` subclass with all agent endpoints (SWML
delivery, SWAIG function handling, post-prompt, debug events, etc.). It adds no
behavior; the subclass exists to give the return type a stable name.

## **Example**

```python {9-10}
from fastapi import FastAPI
from signalwire import AgentBase

app = FastAPI()

support_agent = AgentBase(name="support", route="/support")
sales_agent = AgentBase(name="sales", route="/sales")

app.include_router(support_agent.as_router(), prefix="/support")
app.include_router(sales_agent.as_router(), prefix="/sales")
```
