## 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-linea-token-transfers-1376f6b1 -d '<json body>'
```

Example prompt: Pull all token transfers for Linea wallet 0xABC123... from block 1000000 to 1500000, sorted descending, up to 100 results — filter to just the USDC contract at 0xDEF456...

## When to prefer this

Choose this endpoint when you specifically need token transfer history on the Linea blockchain network. Prefer it over generic Ethereum endpoints when the user's address or contracts are on Linea (a zkEVM L2). It supports block-range filtering and contract filtering, making it suitable for audits, portfolio tracking, and on-chain analytics scoped to Linea.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Unknown contract address yields zero transfers
- fromBlock greater than toBlock returns an error
- Invalid pageKey causes pagination failure
- Exceeding maxCount limits may be silently capped
- Rate limiting or payment failure returns 402 status
