How to connect

The API is OpenAI-compatible: the official SDKs, LangChain and any client with a "base URL" field work.

import OpenAI from 'openai'

const client = new OpenAI({
  baseURL: 'https://getmegabrain.com/api/gateway/v1',
  apiKey: process.env.MEGABRAIN_API_KEY,
})

const response = await client.chat.completions.create({
  model: 'openai/o3-pro',
  messages: [{ role: 'user', content: 'Hello!' }],
})
