## 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 hyperliquid-token-balances-api-0dd66feb -d '<json body>'
```

Example prompt: What token balances does wallet 0xAbC123...def456 currently hold on Hyperliquid? Include balances for contract addresses 0x111... and 0x222... if you can.

## When to prefer this

Use this endpoint when you need to query token balances specifically on the Hyperliquid network for a given wallet. Prefer it over generic multi-chain balance APIs when the user is explicitly working within the Hyperliquid ecosystem, especially for DeFi portfolio tracking, position monitoring, or auditing token holdings on that specific chain.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Contract addresses that don't exist on Hyperliquid return zero or null balances
- Network or API downtime results in a timeout or 5xx error
- Unrecognized contract address format may cause a parsing error
- Owner address with no Hyperliquid activity returns an empty balance list
