## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stableemail-delete-e0394ba4 -d '<json body>'
```

Example prompt: Delete the inbox 'support' on my StableEmail subdomain 'mycompany' — I no longer need that forwarding address.

## When to prefer this

Use this endpoint when you need to permanently remove a specific email inbox (localPart) from a StableEmail-managed subdomain. Prefer this over the single-message delete endpoint when you want to remove the entire inbox rather than individual messages. Ideal for cleanup workflows, deprovisioning user accounts, or retiring unused forwarding addresses on a custom subdomain.

## Known failure modes

- Inbox or subdomain not found — returns error if the localPart or subdomain does not exist
- Invalid localPart format — localPart must match pattern ^[a-z0-9][a-z0-9._+-]{0,62}[a-z0-9]$
- Invalid subdomain format — subdomain must be lowercase alphanumeric with hyphens, no consecutive hyphens
- Inbox already deleted — attempting to delete a non-existent inbox may return an error
- Unauthorized deletion — if the subdomain is not owned or verified by the caller

## How this service works
