OpenClaw Codex OAuth returning billing errors despite valid account

OpenClaw Codex OAuth broken with billing error

A user reports that OpenClaw's Codex OAuth integration has stopped working after functioning correctly approximately one week ago. The primary error returned is a 429 status with the message: "Your account is not active, please check your billing details." An alternative 429 error of "api limit reached" is also mentioned, but the user confirms no API limit is showing on their OpenAI usage page.

Notably, the exec command works fine, confirming that the underlying Codex authentication is valid. The issue appears to be isolated to the OAuth flow within OpenClaw.

Specific error details and logs

The user provided specific logs from attempts to spawn a sub-agent using different models via the OpenAI Codex provider:

• Model: openai-codex/gpt-5.4 | Error: "429 Your account is not active, please check your billing details"
• Model: openai-codex/gpt-5.2 | Error: "429 Your account is not active, please check your billing details"

In contrast, running acpx exec successfully generated valid Python code and reported: "CLI Version: OpenAI Codex v0.113.0, Model: gpt-5.3-codex, Status: ✅ Codex CLI installed, authentication is valid."

Troubleshooting steps attempted

The user has tried several methods to resolve the issue without success:

• Renewed Codex auth using openclaw auth --renew.
• Downgraded OpenClaw through versions .22, .23, and .13, with the same error occurring on all versions.
• Removed and re-added Codex auth on all agents.
• Verified billing and payment method on the OpenAI dashboard, confirming payment is valid.
• Checked the OpenAI usage page, finding no API limit or spending alerts.

The user's question suggests a potential cause: a change on OpenAI's end about a week ago, or a separate OAuth billing flag for Codex versus the regular API.
