FormatWhere to set it up
OpenAI Chat, Anthropic Messageslibrechat.yaml file → endpoints.custom (key in .env via ${VAR}); for the Anthropic format, use provider: 'anthropic'

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/messages, then use that ID in the configuration. For agents, also check tool support and the features required by your client version.

endpoints:
  custom:
    - name: 'Ailoot'
      apiKey: '${AILOOT_API_KEY}'
      baseURL: 'https://api.ailoot.ai/v1'
      models:
        default: ['gpt-6.1-sol', 'claude-sonnet-5-5', 'deepseek-v4-pro']
        fetch: true
      titleConvo: true
      titleModel: 'gpt-6.1-sol'
      modelDisplayLabel: 'Ailoot'
    - name: 'Ailoot Claude'
      provider: 'anthropic'
      apiKey: '${AILOOT_API_KEY}'
      baseURL: 'https://api.ailoot.ai'
      models:
        default: ['claude-sonnet-5-5']
        fetch: false
# .env: AILOOT_API_KEY=sk-...

Example model: gpt-6.1-sol. 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.ai without /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.
