| Method | Scope | What it does |
| --- | --- | --- |
| [`money.store_purchases.verify`](/docs/api/store_purchases/verify) | `billing:write` | Verifies a store purchase with the store, binds it to the subject, and returns its record and a signed grant. Re-verifying returns the same record and grant. Called from the app's server with a secret key that holds `billing:write`; a publishable key cannot call it. |
| [`notify.mailboxes.delete`](/docs/api/mailboxes/delete) | `notify:write` | Deletes a mailbox and its inbound email. |
| [`sandboxes.leases.create`](/docs/api/leases/create) | `sandboxes:write` | Creates a lease: granted now and returned READY (or GRANTED when `wait_ready` is false), or refused with a typed error. There is no queue. |
| [`sandboxes.volumes.delete`](/docs/api/volumes/delete) | `sandboxes:write` | Deletes a volume and destroys its data. Refused RESOURCE_IN_USE while it is attached. |
