## 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-mpp-69d1d6e9 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to extend an already-created agmail inbox for another 24 hours using the MPP (Micropayment Protocol) payment method with stablecoins. Choose this over the x402 renew variant when your agent infrastructure is integrated with MPP rather than x402. Prefer this over creating a new inbox when you want to maintain continuity of the same inbox_id and email address for your agent.

## Known failure modes

- Invalid inbox_id format (must match ^ib_[0-9a-f]{12}$) — request rejected
- Wrong or missing secret — authentication failure
- Payment settlement failure or insufficient USDC balance — renewal not applied
- Inbox not found or already expired — renewal cannot be queued
- MPP protocol error — payment channel unavailable

## 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 being renewed, the plan name ('24h'), a status of 'queued' indicating the extension will be applied once payment settles (typically within a minute), and a 'next' field with instructions on how to check the updated inbox status via a GET endpoint.
