OpenAI Chat, OpenAI ResponsesIn Agent: model: { id: "<provider>/<model>", url: "<baseURL>", apiKey, api?: "chat" | "responses" }

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

import { Agent } from "@mastra/core/agent";
const agent = new Agent({
  id: "ailoot-agent",
  name: "Ailoot Agent",
  instructions: "Respond in Russian",
  model: {
    id: "ailoot/claude-sonnet-5-5",
    url: "https://api.ailoot.ai/v1",
    apiKey: process.env.AILOOT_API_KEY
    // api: "responses"  // only for models with the responses method
  }
});

This configuration reads the key from the environment variable AILOOT_API_KEY. Set it before starting the application:

export AILOOT_API_KEY="sk-..."   # add to ~/.zshrc or ~/.bashrc

Example model: ailoot/claude-sonnet-5-5, ailoot/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).
  • 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.
