## 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 agmail-inbox-renew-1-hour-x402-bd7e9202 -d '<json body>'
```

Example prompt: Renew my agmail inbox ib_0123456789ab for another hour — use secret 'mysecret42' and pay the $0.02 USDC via x402.

## When to prefer this

Use this endpoint when you have an existing agmail inbox (identified by an ib_XXXXXXXXXXXX ID) that is about to expire and you need to extend it by exactly one hour using an x402 stablecoin payment. Prefer this over creating a new inbox when continuity of the same inbox address matters (e.g. you are waiting for an email to that specific address). This is the x402 payment variant; if using MPP, use the corresponding MPP sibling endpoint.

## Known failure modes

- Invalid inbox_id format (must match ^ib_[0-9a-f]{12}$) — returns 4xx validation error
- Wrong or missing secret — returns 401 or 403 unauthorized
- Payment not included or insufficient USDC amount — returns 402 Payment Required
- Inbox does not exist or has been permanently expired — returns 404
- x402 payment settlement delay — status remains 'queued' until blockchain confirmation

## How this service works

Receive-only email inboxes for AI agents, by the hour. Pay in stablecoins with x402 or MPP; one call returns the code or the link.

## Output

Returns a JSON object with the inbox_id, the plan ('1h'), a status of 'queued' indicating the renewal is pending payment settlement, and a 'next' field with instructions on how to check the updated inbox status (typically via a GET endpoint). The actual extension applies once the x402 payment settles, usually within a minute.
