Full guide
| Format | Where to set it up |
|---|---|
| OpenAI Chat, OpenAI Responses, Anthropic Messages | ChatOpenAI(base_url=...) or the OPENAI_API_BASE / OPENAI_BASE_URL environment variables; ChatAnthropic(base_url=...) or ANTHROPIC_API_URL / ANTHROPIC_BASE_URL |
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, POST /v1/messages, then use that ID in the configuration. For agents, also check tool support and the features required by your client version.
import os
from langchain_openai import ChatOpenAI
llm = ChatOpenAI(model="gpt-6.1-sol", base_url="https://api.ailoot.ai/v1", api_key=os.environ["AILOOT_API_KEY"])
print(llm.invoke("Hello").content)
from langchain_anthropic import ChatAnthropic
claude = ChatAnthropic(model="claude-sonnet-5-5", base_url="https://api.ailoot.ai", api_key=os.environ["AILOOT_API_KEY"])Example model: gpt-6.1-sol, qwen3.8-max (ChatOpenAI); claude-sonnet-5-5 (ChatAnthropic). 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). - For the Anthropic format, the URL is
https://api.ailoot.aiwithout/v1. - 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.
