## 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-boba-network-token-transfers-60808576 -d '<json body>'
```

Example prompt: Show me all token transfers for Boba Network wallet 0xAbC123... from block 1000000 to 1050000, sorted ascending, and limit it to 25 results for just the USDT contract 0xDef456...

## When to prefer this

Use this endpoint when you specifically need token transfer history on the Boba Network (an Ethereum Layer 2 optimistic rollup). Prefer this over generic Ethereum endpoints when the target wallet activity is on Boba, and over manual RPC calls when you need indexed, filterable, paginated transfer history without running your own node.

## Known failure modes

- Invalid wallet address format returns a 400 error
- Unrecognized contract address yields empty results
- Invalid block range (fromBlock > toBlock) may return an error or empty set
- Missing required owner field results in a validation error
- Expired or invalid pageKey causes pagination failure
- Network timeout or upstream indexer unavailability returns a 5xx error
