When the user provides a CarsXE API key or asks to configure the plugin:
Validate the key against the CarsXE API:
GET https://api.carsxe.com/v1/auth/validate?key=<USER_PROVIDED_KEY>&source=codex_plugin
Persist the validated key for future sessions by writing it to the plugin config file using Node.js:
node -e "
const fs = require('fs');
const os = require('os');
const path = require('path');
const dir = process.env.PLUGIN_DATA || process.env.CLAUDE_PLUGIN_DATA || path.join(os.homedir(), '.carsxe');
fs.mkdirSync(dir, { recursive: true });
fs.writeFileSync(path.join(dir, 'config.json'), JSON.stringify({ api_key: process.env.CARSXE_KEY_INPUT }));
console.log('Saved to ' + path.join(dir, 'config.json'));
" --env CARSXE_KEY_INPUT=<USER_PROVIDED_KEY>
This uses an environment variable to pass the key to the script, avoiding inline credential exposure.
Set CARSXE_API_KEY for the current session so all skills work immediately without restarting:
CARSXE_API_KEY with the validated value.Confirm:
"CarsXE API key validated and saved. Future sessions will load it automatically."
Verify only: If the user asks to verify their current key without changing it, call the validate endpoint with the existing CARSXE_API_KEY value and report the result.
