## 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 mail-cusethejuice-com-9fcb71ee -d '<json body>'
```

Example prompt: Reply-all to message ID abc123 in my INBOX folder of my CuseTheJuice mailbox (john@cusethejuice.com, username john, password mypass) with the body: 'Thanks everyone, confirmed for Thursday.'

## When to prefer this

Use this endpoint when an AI agent needs to programmatically respond to an existing email thread and include all original recipients (To and Cc), preserving the conversation chain with quoted original body. Prefer over a plain send endpoint when the task is to reply within an ongoing conversation rather than initiating a new message.

## Known failure modes

- Invalid credentials (wrong email/username/password) — authentication failure response
- Message ID not found in the specified folder — message not found error
- Insufficient USDC balance for x402 payment — 402 payment required error
- Malformed email address format — validation error
- Missing required fields (message_id, credentials) — 400 bad request
- SMTP delivery failure for one or more recipients — partial or full send failure
