## 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-kaia-token-balances-76c5de1f -d '<json body>'
```

Example prompt: What are all the token balances for the Kaia wallet address 0xAbC123...def456? Also check balances for these specific token contracts: 0xToken1... and 0xToken2....

## When to prefer this

Choose this endpoint when you need on-chain token balance data specifically from the Kaia blockchain network. It supports filtering by multiple contract addresses in a single call, making it efficient for portfolio checks and eligibility verifications. Prefer this over generic multi-chain aggregators when Kaia-specific speed and accuracy are required.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Contract address array contains invalid addresses causing partial or full failure
- Wallet address with no token holdings returns empty balance list
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 protocol blocks the request

## 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 held by the specified wallet owner on the Kaia blockchain, including token amounts and associated contract details. When contract addresses are provided, results are filtered to only those specific tokens.
