| Format | Where to set it up |
|---|---|
| OpenAI Chat | Profile → Settings → Model Providers → OpenAI Compatible (Base URL and API Key fields; OPENAI_COMPATIBLE_BASE_URL and OPENAI_COMPATIBLE_API_KEY environment variables). Alternatively: OpenAI component → OpenAI API Base field |
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, then use that ID in the configuration. For agents, also check tool support and the features required by your client version.
Settings → Model Providers → OpenAI Compatible:
Base URL: https://api.ailoot.ai/v1
API Key: sk-...
or through environment variables:export OPENAI_COMPATIBLE_BASE_URL="https://api.ailoot.ai/v1"
export OPENAI_COMPATIBLE_API_KEY="sk-..."
Then select OpenAI Compatible → claude-sonnet-5-5 in the Language Model / Agent componentsExample model: claude-sonnet-5-5, gpt-6.1-sol, nemotron-3-embed (Embedding Model). 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.
