ScaleMax for Codex

Connect Codex CLI to a ScaleMax OpenAI-compatible route.

Use Codex with an OpenAI-capable ScaleMax key and the base URL that matches its billing mode. The ScaleMax CLI can configure the connection and verify it with a small billable request, or you can follow the manual Codex guide.

How it fits

Two billing modes, one Codex workflow.

OpenAI token key

Use this when you want a fixed prepaid token allowance for supported OpenAI-family models. The Codex base URL is the token-budget OpenAI-compatible route.

API-credit key

Use this when you want a published-price USD credit balance that can also cover supported Claude-compatible routes. Codex uses the API-credit OpenAI-compatible route.

Automatic or manual

The ScaleMax installer detects Codex configuration and writes the matching provider settings after authentication. The manual guide shows the same settings when you prefer to review each field.

Configuration routes

Codex base URLs.

Both routes are OpenAI-compatible. Choose exactly one based on the key you purchased.

OpenAI token key

https://api.scalemax.pro/token/v1

Recommended for a prepaid OpenAI token allowance.

API-credit key

https://api.scalemax.pro/v1

For a prepaid USD credit balance.

Workflow

Set up Codex without guessing.

  1. 01

    Install ScaleMax

    Install the published ScaleMax CLI, sign in with the API key you intend to use, and let it detect Codex.

  2. 02

    Apply the Codex configuration

    Select Codex in the setup flow. The installer chooses /v1 or /token/v1 from the authenticated key type.

  3. 03

    Verify before a long task

    Run scalemax doctor, which includes a small billable verification request, then run scalemax models. Use a model ID returned to that same key.

  4. 04

    Keep the error context

    If a request fails, save the status code, request ID, selected model ID, and Codex version for support.

Clear boundaries

What this page does and does not promise.

  • Codex support means ScaleMax exposes an OpenAI-compatible route and documented configuration for Codex.
  • The model picker must use an ID returned by your authenticated ScaleMax catalog.
  • A displayed model name and its copyable API ID are separate; use the API ID in configuration.
  • Availability and optional capabilities can change with the active model route, so send a small billable verification request before a large run.

Continue with a focused resource

Configure Codex from the key, not from memory.

Start with guided setup for automatic route selection, then verify the authenticated model list before sending a full coding task.
