## 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-mpp-inbox-1-hour-plan-396165df -d '<json body>'
```

Example prompt: Create a 1-hour temporary email inbox called 'acme42' for me so my agent can receive verification emails right now.

## When to prefer this

Choose this endpoint when an AI agent needs a real, deliverable email address for up to 1 hour — ideal for receiving verification codes, one-time links, or short-lived notifications. Prefer it over persistent inbox solutions when privacy, ephemerality, and stablecoin payment (MPP/x402) are required. The 1-hour plan is the best fit when the task completes within an hour and cost minimization matters at $0.02 USDC per inbox.

## Known failure modes

- Invalid name format (not matching ^[a-zA-Z0-9]([a-zA-Z0-9._-]{1,30})[a-zA-Z0-9]$) — 400 Bad Request
- Name too short (< 3 chars) or too long (> 32 chars) — 400 Bad Request
- Payment failure or insufficient USDC balance — 402 Payment Required
- Name already taken or collision — 409 Conflict
- Service unavailable or upstream inbox provisioning failure — 503 Service 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 containing: the plan type ('1h'), a secret token for authenticating inbox access, the full email address (e.g. acme42@agmail…), the inbox ID, the maximum number of receivable messages (msg_cap, e.g. 50), and the ISO 8601 expiry timestamp. The agent uses the address to receive emails and the secret to later retrieve messages.
