## 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-3e6de6dd -d '<json body>'
```

Example prompt: Forward message ID abc123 from my CuseTheJuice mailbox (user@mail.cusethejuice.com, username 'alice', password 'secret99') to bob@example.com and cc carol@example.com, with a note at the top saying 'Thought you should see this.'

## When to prefer this

Use this endpoint when an AI agent needs to forward a specific, already-received message from a CuseTheJuice mailbox to one or more recipients, optionally prepending a custom note. Prefer this over a generic send/compose endpoint when the operation is a true forward (preserving original content with Fwd: prefix) rather than composing a new message. Requires x402 payment in Base USDC per call.

## Known failure modes

- Missing required auth fields (username/password) returns 401 or 402 payment required
- No recipient specified (to/cc/bcc all empty) returns validation error
- Invalid or non-existent message_id returns 404 or error
- Payment not completed via x402/Base USDC returns 402 with payment instructions
- Invalid email format for recipient or sender returns 400
- Incorrect credentials return authentication failure
