## 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-24-hour-receive-only-email-inbox-68d419c0 -d '<json body>'
```

Example prompt: Create a 24-hour temporary email inbox named 'acme42' for my agent so it can receive emails — I want the inbox address, secret, and when it expires.

## When to prefer this

Choose this endpoint when an AI agent needs a temporary, receive-only email inbox lasting 24 hours and you want to pay with stablecoins (USDC via x402 or MPP) with a single API call. Prefer this over full email-service integrations when you don't need sending capability, don't want to manage persistent inboxes, and want a crypto-native payment flow with no credit card or OAuth setup.

## Known failure modes

- Invalid name format (must match ^[a-zA-Z0-9]([a-zA-Z0-9._-]{1,30})[a-zA-Z0-9]$) — returns 400 validation error
- Name already taken — may return 409 conflict
- Insufficient stablecoin balance or failed x402 payment — returns 402 Payment Required
- Name too short (< 3 chars) or too long (> 32 chars) — returns 400
- Service unavailable or rate-limited — returns 503 or 429

## 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 plan duration (e.g. '24h'), a secret token for authenticating inbox access, the provisioned email address (e.g. acme42@agmail…), a message cap (max emails receivable), a unique inbox_id, and an ISO 8601 expiry timestamp.
