Integration

Swap base URL and keep the OpenAI-style SDK pattern.

unlimitedcodex is designed for OpenAI-compatible clients: keep familiar request shapes, set the delivered base URL and key, then validate models, chat, embeddings, and image endpoints.

  • OpenAI-compatible client pattern
  • Base URL and API key delivered after checkout
  • Chat/completions, embeddings, model-list, images where supported
  • Flat weekly or monthly access

Setup steps

Step 1

Get the delivered credentials

After checkout, wait for manual provisioning. Your setup email includes the base URL, API key, setup files, and model IDs.

Step 2

Change the SDK base URL

Keep your OpenAI-compatible request shape and change the client base URL to the delivered unlimitedcodex endpoint.

Step 3

Change the API key

Replace the direct provider key with your delivered unlimitedcodex key. Store it server-side and avoid exposing it in browser code.

Step 4

Run endpoint checks

Test /models, chat/completions, embeddings, image generation where supported, and retry behavior before a production-like run.

Example configuration

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.UNLIMITEDCODEX_API_KEY,
  baseURL: process.env.UNLIMITEDCODEX_BASE_URL
});

const response = await client.chat.completions.create({
  model: process.env.UNLIMITEDCODEX_MODEL!,
  messages: [{ role: "user", content: "Run a small smoke test." }]
});

FAQ

Do I need to rewrite my SDK calls?

Usually no. The normal migration pattern is to swap the API key, base URL, and model ID while keeping the OpenAI-compatible request shape.

What should I test first?

Test /models, chat/completions, embeddings, image generation where supported, streaming if your app uses it, and retry behavior under the 4 concurrent connection limit.

Does flat access mean no limits at all?

No. The package includes unlimited token consumption with a concrete operational limit of 4 concurrent connections.
