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.

OpenAI-compatible:
  Provider name: Ailoot
  Base URL: https://api.ailoot.ai/v1
  API key: sk-...
Anthropic-compatible:
  Provider name: Ailoot Claude
  Base URL: https://api.ailoot.ai
  API key: sk-...
Models: loaded from {base_url}/models or + manually: claude-sonnet-5-5

Example model: claude-sonnet-5-5. 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.
