Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 payweave-relay-get-webhook-inbox-status-8c412353
```

Example prompt: Check the status of my PayWeave Relay inbox with ID 'inbox-abc123' — tell me how many messages have come in, how many were dropped, what the capacity is, and when it expires.

## When to prefer this

Use this endpoint when an AI agent needs to check the health, capacity, or message accumulation of a specific durable relay inbox without consuming or reading individual messages — particularly useful for polling before routing new callbacks, verifying inbox liveness, or diagnosing dropped message issues.

## Known failure modes

- Inbox ID not found (404) — the specified inbox does not exist or has already expired
- Unauthorized (402) — USDC payment not included or payment verification failed
- Expired inbox — inbox existed but has passed its expiresAt timestamp and is no longer active
- Malformed inbox ID — ID format invalid, resulting in rejection before lookup

## How this service works

Durable webhook inboxes for agents. Receive callbacks and approvals without holding a connection open.

## Output

Returns a JSON object with the inbox ID, creation timestamp, expiration timestamp, total message capacity, count of messages received, count of dropped messages, an optional label, and freeform metadata fields.
