## 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 nexari-letter-order-status-7677a53c
```

Example prompt: Can you check the status of my Nexari letter order with ID LTR-20240512-007 and tell me whether it's been sent yet or is still being processed?

## When to prefer this

Use this endpoint when you need to check the processing or dispatch status of a specific physical letter order previously created via the Nexari letter service (POST /letter/quote and subsequent steps). This is the correct endpoint if you have a letter_id and want to know whether Nexari has received the order or already sent it via Deutsche Post. Not suitable for creating new letter orders, getting quotes, or tracking delivery to the end recipient.

## Known failure modes

- Invalid or non-existent letter_id returns a 404 or error response
- Missing letter_id path parameter causes a 400 bad request
- Letter order not yet created or payment not completed may result in a not-found error
- Temporary service outage may return a 5xx error

## How this service works

Status eines Briefauftrags (received oder sent). Status of a letter order.

## Output

Returns the current status of the specified letter order, indicating either 'received' (the order has been accepted and is being processed) or 'sent' (the letter has been printed and dispatched via Deutsche Post). May also include the letter_id and any additional metadata about the order.
