Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|

| CRON402_NETWORK | — | — | CAIP-2 network id. Default eip155:8453 (Base mainnet); use eip155:84532 for Sepolia. |
| CRON402_API_URL | — | — | cron402 API base URL. Defaults to the production Worker. |
| CRON402_STATE_DIR | — | — | Directory where created job ids are remembered so list_crons can recover them. Defaults to ~/.cron402. |
