## 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-24h-renew-d44d6f18 -d '<json body>'
```

Example prompt: Renew my agmail inbox ib_0123456789ab for another 24 hours — use my secret to authenticate and queue the extension.

## When to prefer this

Use this endpoint when you already have an existing agmail inbox (identified by its inbox_id) that is approaching expiry and you want to extend it by 24 hours without creating a new one. Prefer this over creating a new inbox when continuity of the same email address matters (e.g. awaiting messages sent to that specific address). Choose this if you are operating in an x402 or MPP stablecoin payment context.

## Known failure modes

- Invalid or malformed inbox_id (must match ^ib_[0-9a-f]{12}$) returns a 4xx error
- Wrong or missing secret results in authentication failure
- Payment not settled causes the renewal to remain in 'queued' state indefinitely
- Inbox already expired before renewal may result in inability to extend
- Network or payment protocol timeout leaves status in uncertain 'queued' state

## 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 status ('queued'), the plan ('24h'), the inbox_id, and a 'next' field with instructions explaining that the renewal will take effect after payment settles (typically around one minute), plus a URL to poll for confirmation.
