Scan For Subscriptions + +Start the gateway, then run: + +```bash +curl -X POST http://localhost:3100/api/subscriptions/scan \ + -H "Authorization: Bearer " +``` + +The scan checks the known subscription catalog and reports: + +- whether the CLI is installed +- whether authentication can be detected +- whether a bridge is already running +- which model IDs the gateway can expose +- whether the subscription can be joined or spawned + +## 4.
