## 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-858fa152 -d '<json body>'
```

Example prompt: Prepare a one-signature batch onboard-and-bond transaction for my AI agent on Base using Vaultfire's BatchOnboarder so I can register it under ERC-8004 and post a bond in a single EIP-7702 tx — I'll sign it in my wallet.

## When to prefer this

Use this endpoint when you need to register an ERC-8004 AI agent identity AND post a Vaultfire bond atomically in a single EIP-7702 transaction on Base, saving gas and UX friction compared to calling register and bond as separate transactions. Prefer this over individual registration or bonding endpoints when onboarding a new agent from scratch.

## Known failure modes

- Invalid or missing agent address returns 400 with field-level error
- Malformed bond parameters cause transaction preparation failure
- Base network RPC unavailability causes 503 service error
- x402 payment header missing or invalid USDC amount returns 402 payment required
- Agent already registered may cause contract-level revert indication in response
- Insufficient bond amount specified triggers validation error

## How this service works

Tx-prepare for VaultfireBatchOnboarder.onboardAndBond() — EIP-7702 one-sig register + bond on Base. Returns unsigned transaction; caller signs in wallet.

## Output

Returns an unsigned EIP-7702 transaction object targeting VaultfireBatchOnboarder.onboardAndBond() on Base mainnet, ready for the caller to sign locally in their wallet. No on-chain state is modified until the caller signs and broadcasts.
