## 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-apechain-token-transfers-ded39c6b -d '<json body>'
```

Example prompt: Pull all token transfers for wallet 0xAbC123... on ApeChain from block 1000000 to 1500000, sorted descending, and limit to 100 results — include only transfers from the contract 0xTokenContract...

## When to prefer this

Use this endpoint when you specifically need token transfer history on the ApeChain network. It supports filtering by contract address and block range, making it ideal for auditing wallet activity, tracking token flows for specific contracts, or building paginated transfer history views for ApeChain-based assets. Prefer this over generic blockchain explorers when you need programmatic, pay-per-call access without API key setup.

## Known failure modes

- Invalid or malformed owner address returns an error
- Block range too large may result in timeout or truncated results
- Invalid contractAddress format causes request rejection
- Missing required owner field returns validation error
- pageKey from a different query context may return no results or an error
- ApeChain node unavailability returns 503 or timeout
