## When to prefer this

Use this endpoint when you need to check whether a StableEmail inbox is still active or when it expires, before attempting to send or receive mail through it. Prefer this over the general brand docs when you have a specific username and need a programmatic status response.

## Known failure modes

- Username not found — inbox does not exist for the given username
- Missing required username parameter — returns validation error
- Service unavailable — upstream API unreachable
- Inbox already expired — returns expired status with past expiry date

## How this service works
