## 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-crypto-mailbox-creator-ea293ea7 -d '<json body>'
```

Example prompt: Create an email mailbox called 'mybot' at clawmail.xyz and link it to my Ethereum wallet 0xAbC1234567890abcdef1234567890abcdef123456.

## When to prefer this

Choose this endpoint when you need to give an AI agent or LLM a dedicated, persistent email identity linked to an Ethereum wallet. It is uniquely suited for web3-native or crypto-adjacent agent workflows where mailbox ownership can be tied to an on-chain address. Prefer it over general email providers when the agent ecosystem requires x402 micropayment-based provisioning or when you want an agent-purpose-built inbox at the @clawmail.xyz domain.

## Known failure modes

- Address already taken — the requested local-part is already registered
- Invalid wallet address — not a valid 0x-prefixed 42-character Ethereum address
- Payment failure — the $1 USDC x402 payment was not completed or rejected
- Invalid address format — local-part contains disallowed characters
- Missing required fields — address or walletAddress not provided

## Output

A confirmation that the email mailbox (e.g. myagent@clawmail.xyz) has been created and is ready to receive messages, likely including the full email address and any associated mailbox details.
