## 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 ragradar-mev-data-by-chain-and-address-c7910279
```

Example prompt: Can you pull the MEV activity data for wallet address 0xABC123... on Base using RagRadar?

## When to prefer this

Use this endpoint when you need MEV-specific on-chain intelligence for a wallet or contract address on Base, Arbitrum, or Solana, and are willing to pay a small $0.02 USDC micropayment per query via x402. Prefer this over general blockchain explorers when MEV analysis is the specific focus.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed or invalid address format results in a bad request error
- Payment not received or insufficient USDC micropayment causes a 402 response
- Address with no on-chain activity may return empty or minimal data
- Backup domain may have higher latency or intermittent availability

## How this service works
