## 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-temporary-email-inbox-4-hour-plan-d12a6364 -d '<json body>'
```

Example prompt: Set up a temporary 4-hour email inbox for my agent with the name 'myagent42' so it can receive incoming messages during this task.

## When to prefer this

Choose this endpoint when your AI agent needs a real, receive-only email address for a short 4-hour window — ideal for catching verification emails, password resets, or confirmations during automated workflows. Prefer it over longer-duration plans when cost matters and the task completes within hours. Use it over generic email APIs when you need pay-per-use stablecoin billing with no account setup.

## Known failure modes

- Invalid name format (does not match ^[a-zA-Z0-9]([a-zA-Z0-9._-]{1,30})[a-zA-Z0-9]$) returns a 400 error
- Name too short (under 3 chars) or too long (over 32 chars) returns validation error
- Payment failure via x402 or MPP returns a 402 Payment Required response
- Name already taken may return a conflict error
- Service unavailable or quota exceeded returns 5xx error

## 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
