# GET /api_esim/verifyResourceByApiCode — Check inventory

> Check whether sufficient card inventory exists for a package by its apiCode. Returns 1 if resources are available, 0 if insufficient. Use before bulk orders.

Same as [Verify Resources](/api-reference/verify-resources) but uses the package's `apiCode` instead of separate `skuid` + `priceid` values. The `apiCode` is returned by the package listing endpoints (e.g. `"40-0-3-1-G"`).
