## 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 phantom-api-boba-network-token-balances-8fd192bb -d '<json body>'
```

Example prompt: What token balances does wallet 0xAbc123...def on Boba Network currently hold? Check specifically for USDC at 0xB12BFEa...and OMG at 0xd26114...

## When to prefer this

Choose this endpoint when you specifically need token balance data on the Boba Network (an Ethereum Layer 2 OVM chain). It is ideal for per-address portfolio lookups, DeFi audits, or multi-token balance checks on Boba. Prefer this over generic Ethereum balance APIs when the target chain is Boba, and over full node queries when you want a simple pay-per-call REST interface without managing RPC infrastructure.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Contract address not deployed on Boba Network returns zero balance or error
- Network congestion or RPC unavailability causes timeout
- Unsupported token standard (non-ERC-20) may not be returned
- Payment failure via x402 protocol blocks the request entirely

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

Returns a structured list of token balances for the specified wallet address on Boba Network, including token amounts, decimals, and contract details for each queried token (or all held tokens if no contract addresses are specified).
