## 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 synapse-api-hyperliquid-token-transfers-b9193a12 -d '<json body>'
```

Example prompt: Pull all token transfers for the Hyperliquid wallet 0xAbC123... from block 1000000 to block 1050000, sorted descending, and return up to 50 results.

## When to prefer this

Use this endpoint when you need to query historical token transfer events for a specific wallet or contract address on the Hyperliquid network, especially when you need block-range filtering, pagination, or sorting. Prefer it over generic blockchain explorers when you need programmatic, pay-per-call access via x402 without API key management.

## Known failure modes

- Invalid owner address format returns an error or empty result
- Invalid block range (fromBlock > toBlock) may return an error or empty set
- Unknown or unsupported contract address returns empty transfers
- Invalid pageKey causes pagination failure or error
- Missing required owner field returns a validation error
- Network or upstream Hyperliquid node unavailability causes 5xx errors
