Pydantic AI
MarkdownAgent framework · OpenAI Chat, OpenAI Responses
Full guide
| Format | Where to set it up |
|---|---|
| OpenAI Chat, OpenAI Responses | OpenAIProvider(base_url=..., api_key=...) with OpenAIChatModel for Chat Completions or OpenAIResponsesModel for Responses, or the OPENAI_BASE_URL variable |
Setup
Copy the configuration and replace sk-... with your key from the Ailoot Dashboard. Prefer storing the key in the environment variable AILOOT_API_KEY, if the application supports it.
Before starting, request GET /v1/models with your Ailoot key. Choose an exact model ID whose methods include POST /v1/chat/completions, POST /v1/responses, then use that ID in the configuration. For agents, also check tool support and the features required by your client version.
import os
from pydantic_ai import Agent
from pydantic_ai.models.openai import OpenAIChatModel
from pydantic_ai.providers.openai import OpenAIProvider
model = OpenAIChatModel("deepseek-v4-pro",
provider=OpenAIProvider(base_url="https://api.ailoot.ai/v1", api_key=os.environ["AILOOT_API_KEY"]))
agent = Agent(model)
print(agent.run_sync("Hello").output)Example model: deepseek-v4-pro, gpt-6.1-sol (for OpenAIResponsesModel). Choose any other model from the catalog — check that it supports the format you need.
Good to know
Test
- For the OpenAI format, the URL is
https://api.ailoot.ai/v1(or the full path if the application asks for a full URL). - Ask a short question. If you get an error, check the code and Request ID, then consult Errors and limits.
- 404 immediately after setup almost always means the URL is wrong: an extra or missing
/v1. - 402 — insufficient balance for the reserve. Agents reserve more than chat: why.
