Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-gateway-cross-chain-balance-bazaar-137c959d -d '<json body>'
```

Example prompt: What's the cross-chain token balance for wallet 0xAbC123...def456 across all supported networks? Use the cross_chain_balance tool.

## When to prefer this

Choose this endpoint when you need a single aggregated view of a wallet's token holdings across multiple blockchain networks without querying each chain individually. Ideal for DeFi dashboards, portfolio trackers, treasury management agents, and multi-chain reconciliation workflows. Best when the agent needs on-chain data quickly without setting up individual RPC connections per chain.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported blockchain network not included in results
- Payment failure (402) if USDC balance is insufficient for the $0.002 call fee
- Network timeout if a specific chain's RPC is slow or unavailable
- Tool name parameter mismatch returns a catalog error
