## 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-ab3e2b0f
```

Example prompt: Pull the MEV activity report for address 0xABC123... on Base — I want to see if this wallet has been sandwiched or targeted by MEV bots recently.

## When to prefer this

Choose this endpoint when you need MEV-specific intelligence tied to a particular wallet or contract address on a supported chain (Base, Arbitrum, Solana). Prefer this over generic block explorers when you specifically need MEV exposure, sandwich attack detection, or extraction activity signals rather than general transaction history.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed or invalid address format returns an error
- Address has no on-chain history returns empty or minimal result
- Payment not completed via x402 micropayment returns 402 Payment Required
- Network timeout or upstream data unavailability returns 5xx error
- Unsupported chain not among Base, Arbitrum, or Solana returns error

## How this service works

On-chain intelligence for AI agents. 73+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output

A JSON object containing MEV-related intelligence for the queried address on the specified chain, including status and on-chain activity metrics such as sandwich attacks, front-running events, or other extractable value signals.
