CarsXE Plugin for OpenAI Codex

Access the full suite of CarsXE vehicle data APIs directly from OpenAI Codex — decode VINs, look up license plates, get market values, check history, recalls, liens, OBD codes, and more.

Sign up at api.carsxe.com and grab your key from the developer dashboard.

2. Set the CARSXE_API_KEY environment variable

Codex skills read your key from CARSXE_API_KEY. Set it before launching Codex:

# macOS / Linux
export CARSXE_API_KEY="YOUR_API_KEY_HERE"
# Windows (PowerShell)
$env:CARSXE_API_KEY="YOUR_API_KEY_HERE"

Add it to your shell profile to persist it across sessions.
