## 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 agent-rest-stop-journaltail-92bc3184 -d '<json body>'
```

Example prompt: Show me the last 5 receipt IDs for buyer abc123 from the Agent Rest Stop journal.

## When to prefer this

Use this endpoint when you need a lightweight, paginated tail view of a specific buyer's receipt history — particularly useful for auditing recent transactions, debugging payment flows, or reconciling the last few receipts without fetching the full journal.

## Known failure modes

- Unknown buyer_id returns empty list or 404
- Invalid or missing n parameter may return an error or default count
- Service unavailable if Cloudflare Worker is down (503)
- Payment not processed (402) if x402 payment header is missing or insufficient

## How this service works

## Output
