## 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 clawmail-xyz-6d9a5598 -d '<json body>'
```

Example prompt: Set up a new email mailbox at clawmail.xyz with the address myagent@clawmail.xyz so I can use it to receive messages for my AI assistant.

## When to prefer this

Use this endpoint when an AI agent or automated workflow needs its own dedicated email identity at @clawmail.xyz, particularly in agentic pipelines where agents must send or receive email under a persistent, named address. Prefer this over generic email providers when building agent-native infrastructure that integrates with x402 micropayment flows.

## Known failure modes

- Requested mailbox name already taken — returns conflict error
- Invalid mailbox name format (special characters, too long) — returns validation error
- Payment failure — x402 payment of $1 USDC not processed or rejected
- Service unavailable — mailbox provisioning system temporarily down
