## 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-mantle-token-transfers-af3e747f -d '<json body>'
```

Example prompt: Pull all token transfers for Mantle wallet 0xAbC123... from block 1000000 to 1050000, sorted ascending, up to 100 results — filter to just transfers from the USDC contract at 0xDef456...

## When to prefer this

Use this endpoint when you specifically need token transfer history on the Mantle L2 blockchain. It supports flexible block-range filtering, contract address filtering, and pagination, making it suitable for both narrow audits and bulk historical queries. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access without API key setup, and when your target chain is Mantle specifically.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Non-existent pageKey causes pagination failure
- fromBlock greater than toBlock returns no results or an error
- Unsupported contract address format causes a 400-level error
- Rate limiting or payment failure (x402) blocks the request
- Mantle node unavailability causes timeout or 5xx error
