## 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-token-balances-degen-8a12ad11 -d '<json body>'
```

Example prompt: What are the token balances for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045? Also filter it to just show balances for these two tokens: 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and 0xdAC17F958D2ee523a2206206994597C13D831ec7.

## When to prefer this

Prefer this endpoint when you need fast, pay-per-call on-chain token balance lookups without a subscription commitment, especially across a broad range of EVM-compatible networks. It is ideal for agents doing one-off portfolio checks, airdrop eligibility verification, or whale wallet monitoring. Choose this over free RPC calls when you need reliability, breadth across 57+ networks, and structured output rather than raw RPC responses.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported network or token contract returns no data
- Rate limiting or payment failure (x402) prevents the call from completing
- Contract address not found on-chain returns zero or null balance
- Network congestion may cause delayed or stale data

## 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 on-chain token balances for the specified wallet address. When contract addresses are provided, results are filtered to those specific tokens. Response includes token amounts, contract metadata (symbol, decimals), and human-readable balance values across supported blockchain networks.
