## 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-ink-network-token-balances-518812e0 -d '<json body>'
```

Example prompt: Can you check the token balances for wallet 0xAbC123...def on the Ink network, including holdings for contract addresses 0xToken1 and 0xToken2?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call token balance lookups specifically on the Ink blockchain network. It is ideal for agents that need lightweight, on-demand wallet portfolio data without managing a full node or subscription. Prefer it over general-purpose indexers when operating on Ink specifically and when cost-per-call billing via USDC is acceptable.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Unsupported or non-Ink contract addresses return zero balances or errors
- Network timeout if Ink RPC nodes are unresponsive
- Empty array returned if wallet holds no tokens matching the given contracts
- Rate limiting or payment failure if x402 payment header is invalid or insufficient

## 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 list of token balances associated with the specified owner wallet address on the Ink network, optionally filtered by provided contract addresses. Each entry typically includes the token contract address, token symbol or name, balance amount, and decimals.
