## 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 chainray-flash-loan-monitor-d24b6bc4
```

Example prompt: Can you pull up the latest flash loan activity on Ethereum right now? I want to see what's happening on-chain.

## When to prefer this

Use this endpoint when you need real-time or near-real-time flash loan event data for a specific blockchain network, particularly for DeFi security monitoring, exploit detection, or analytics dashboards. Prefer this over generic block explorers when you need structured, agent-consumable flash loan data across 46 chains with pay-per-request pricing.

## Known failure modes

- Unsupported chain parameter returns an error or empty result
- Missing chain parameter may default to a primary network or return a validation error
- Network congestion may delay real-time data
- Payment failure (x402) results in 402 response blocking data access
- Chain with no recent flash loan activity returns empty dataset
