FormatWhere to set it up
OpenAI Chat, Anthropic Messagesopts for yetone/avante.nvim in lazy.nvim: opts.providers.<name> with __inherited_from = 'openai' (a custom OpenAI-compatible provider), or override providers.claude.endpoint; the key comes from the variable specified in api_key_name (AVANTE_* names are supported).

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.

opts = {
  provider = "ailoot",
  providers = {
    ailoot = {
      __inherited_from = "openai",
      endpoint = "https://api.ailoot.ai/v1",
      api_key_name = "AILOOT_API_KEY",
      model = "claude-sonnet-5-5",
    },
    claude = {
      endpoint = "https://api.ailoot.ai",   -- Anthropic Messages, without /v1
      model = "claude-sonnet-5-5",
    },
  },
}
-- in the terminal: export AILOOT_API_KEY=sk-...
-- the claude provider reads AVANTE_ANTHROPIC_API_KEY or ANTHROPIC_API_KEY

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.
