## 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 blockscout-optimism-dispute-games-list-9b35c976
```

Example prompt: Show me the latest Optimism dispute games on chain 10 — I want to see their status, game type, L2 block number, and contract addresses, paginated 25 items at a time.

## When to prefer this

Use this endpoint when you need structured, paginated data about Optimism fault dispute games on a specific OP stack chain via Blockscout's API. Prefer it over general block explorer UIs when automating monitoring, auditing resolution timelines, or programmatically cross-referencing dispute game contracts with on-chain data. It is purpose-built for OP stack dispute game data and does not require authentication beyond per-call payment.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty result
- Pagination index out of range returns empty items array
- Network or upstream node unavailability causes 5xx errors
- Malformed query parameters (non-integer index/items_count) cause 400 errors
- Chain does not support Optimism dispute games returns empty or error response
