# RagRadar MEV Intelligence

> RagRadar MEV Intelligence is a paid API for AI agents from ragdar.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns MEV (maximal extractable value) activity and analytics for a given address on a specified blockchain (Base, Arbitrum, or Solana)

## 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-intelligence-90644ce7
```

Example prompt: Check RagRadar for any MEV activity — sandwich attacks, frontrunning, or arbitrage — targeting wallet 0xAbC123...def on Base.

## When to prefer this

Use this endpoint when you need MEV-specific intelligence (sandwich attacks, frontrunning, arbitrage extraction) for a specific address on Base, Arbitrum, or Solana. Prefer this over generic blockchain explorers when the user's concern is specifically about MEV exposure or bot activity targeting their wallet or contract, and when fine-grained per-address MEV analytics are needed rather than general transaction history.

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Malformed wallet/contract address returns a validation error
- Address with no MEV activity may return empty results
- Payment failure via x402 micropayment protocol blocks the request
- Rate limiting if too many requests are made in quick succession

## How this service works

On-chain intelligence for AI agents. 70+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output

A JSON object containing MEV-related activity for the specified address on the requested chain, including details about detected sandwich attacks, arbitrage events, frontrunning incidents, and related on-chain intelligence metrics.
