## 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 robinhood-token-transfers-lookup-02149bda -d '<json body>'
```

Example prompt: Pull all token transfers for wallet address 0xAbC123... from block 18000000 to 19000000, sorted ascending, and limit results to 100 transfers — filter by the USDC contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48.

## When to prefer this

Use this endpoint when you need to retrieve historical token transfer events for a specific wallet address on-chain, especially when filtering by block range or specific ERC-20 contract addresses. Prefer this over generic blockchain explorers when you need structured, paginated JSON output suitable for agent processing.

## Known failure modes

- Invalid owner address format returns a 400 or empty result
- Unknown contract address yields no transfer records
- fromBlock greater than toBlock causes an error or empty response
- Invalid pageKey causes pagination to fail or restart
- Exceeding maxCount limits may truncate results silently
- Network congestion or indexer lag may return stale data
