## 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 theloopbreaker-com-f7c372ed -d '<json body>'
```

Example prompt: Prepare the transaction for me to transfer my VNS primary name 'myagent.vaultfire' to the address 0xAbC123... — I'll sign it in my wallet myself.

## When to prefer this

Use this endpoint when you need to transfer ownership of a VaultfireNameService primary name to a new wallet address and want an unsigned transaction to sign locally rather than submitting a pre-signed transaction. Prefer this over generic contract call builders when you specifically need the VaultfireNameService.transferName() ABI encoding with Vaultfire Protocol's verified contract addresses across supported chains.

## Known failure modes

- Name not registered or not owned by the specified sender — returns ownership error
- New owner address is invalid or zero address — returns validation error
- VNS contract unavailable or RPC node unreachable — returns upstream error
- Insufficient x402 USDC payment ($0.20) — returns payment required error
- Name is already being transferred or locked — returns state conflict error

## How this service works

Tx-prepare for VaultfireNameService.transferName() — transfer your primary VNS name to a new owner. Returns unsigned transaction; caller signs in wallet.

## Output

Returns an unsigned transaction object containing the encoded VaultfireNameService.transferName() calldata, ready for the caller to sign and broadcast via their wallet. Does not submit or broadcast the transaction.
