## 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-ronin-token-transfers-807d3a96 -d '<json body>'
```

Example prompt: Pull all token transfers for the Ronin wallet address 0xABC123... sorted in descending order, limiting to 50 results, and only include transfers from contract 0xDEF456...

## When to prefer this

Use this endpoint when you specifically need token transfer history on the Ronin blockchain (associated with Axie Infinity and Sky Mavis gaming ecosystem). Prefer this over generic Ethereum endpoints when targeting Ronin-native assets or gaming tokens. Choose this when you need paginated, filterable transfer history with block-range precision rather than a simple balance check.

## Known failure modes

- Invalid or malformed owner address returns an error or empty result
- Invalid block range (toBlock less than fromBlock) may return an error
- Unknown or invalid contract address returns empty transfers
- Payment failure via x402 prevents API access
- Rate limiting or quota exhaustion if max calls exceeded
- Invalid pageKey causes pagination error or restarted results
