Accessing other bots on Poe

The Poe bot query API allows developers to invoke other bots on Poe (which includes bots created by Poe like GPT-3.5-Turbo and Claude-Instant and bots created by other developers) and this access is provided for free so that developers do not have to worry about LLM costs. For every user message, server bot developers get to make up to ten calls to another bot of their choice.
If you are just getting started with server bots, we recommend checking out our quick start guide. The following tutorial is specifically for how you invoke other bots and assumes that you are familiar with the concept of server bots.

Install the Poe FastAPI client

pip install fastapi_poe

Implement the PoeBot class

You have to declare your bot dependencies using the settings endpoint.
async def get_settings(self, setting: fp.SettingsRequest) -> fp.SettingsResponse:
return fp.SettingsResponse(server_bot_dependencies={"GPT-3.5-Turbo": 1})
In your get_response handler, use the stream_request function to invoke any bot you want. The following is an example where we forward the user's query to GPT-3.5-Turbo and return the result.
async def get_response(
self, request: fp.QueryRequest
) -> AsyncIterable[fp.PartialResponse]:
async for msg in fp.stream_request(
request, "GPT-3.5-Turbo", request.access_key
):
yield msg
The final code (including the setup code you need to host this on Modal) that goes into your main.py is as follows:
from __future__ import annotations
from typing import AsyncIterable
from modal import Image, Stub, asgi_app
import fastapi_poe as fp
class GPT35TurboBot(fp.PoeBot):
async def get_response(
self, request: fp.QueryRequest
) -> AsyncIterable[fp.PartialResponse]:
async for msg in fp.stream_request(
request, "GPT-3.5-Turbo", request.access_key
):
yield msg
async def get_settings(self, setting: fp.SettingsRequest) -> fp.SettingsResponse:
return fp.SettingsResponse(server_bot_dependencies={"GPT-3.5-Turbo": 1})
REQUIREMENTS = ["fastapi-poe==0.0.24"]
image = Image.debian_slim().pip_install(*REQUIREMENTS)
stub = Stub("turbo-example-poe")
@stub.function(image=image)
@asgi_app()
def fastapi_app():
bot = GPT35TurboBot()
app = fp.make_app(bot, allow_without_key=True)
return app
To learn how to setup Modal, please follow Steps 1 and 2 in our Quick start. If you already have Modal set up, simply run modal deploy main.py. Modal will then deploy your bot server to the cloud and output the server url. Use that url when creating a server bot on Poe.
Now, before you use the bot, you will have to follow the steps in this article in order to get Poe to fetch your bots settings (one time only after you override get_settings). Once that is done, try to use your bot on Poe and you will see the response from GPT-3.5-Turbo. You can modify the code and do more interesting things (like apply some business logic on the response or conditionally call another API).

How to access the bot query API directly

We also provide a helper function for you to test the bot query API in a lower friction manner.

Install the Poe FastAPI client

pip install fastapi_poe

Get your API Key

Navigate to poe.com/developers and copy your user API key. Note that access to an API key is currently limited to Poe subscribers to minimize abuse.
Usage done with this API key will count against your user account's message limits on Poe, so be sure to only use it for testing and not for cases when other people are using your bot.

Access the bot query API using "get_bot_response"

In your python shell, run the following after replacing the placeholder with your API key.
import asyncio
import fastapi_poe as fp
# Create an asynchronous function to encapsulate the async for loop
async def get_responses(api_key, messages):
async for partial in fp.get_bot_response(messages=messages, bot_name="GPT-3.5-Turbo", api_key=api_key):
print(partial)
# Replace <api_key> with your actual API key, ensuring it is a string.
api_key = <api_key>
message = fp.ProtocolMessage(role="user", content="Hello world")
# Run the event loop
# For Python 3.7 and newer
asyncio.run(get_responses(api_key, [message]))
# For Python 3.6 and older, you would typically do the following:
# loop = asyncio.get_event_loop()
# loop.run_until_complete(get_responses(api_key))
# loop.close()
If you are using an ipython shell, you can instead use the following simpler code.
import fastapi_poe as fp
message = fp.ProtocolMessage(role="user", content="Hello world")
async for partial in fp.get_bot_response(messages=[message], bot_name="GPT-3.5-Turbo", api_key=<api_key>):
print(partial)
