# ChainRay MEV Intelligence

> ChainRay MEV Intelligence is a paid API for AI agents from chainray.online, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Retrieves maximal extractable value (MEV) intelligence and analytics for a specified blockchain network

## Facts

- Endpoint: GET https://chainray.online/mev-intel
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/chainray-mev-intelligence-64ba7ffc

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-mev-intelligence-64ba7ffc
```

Example prompt: What's the current MEV activity on Base — any sandwich attacks or frontrunning going on right now?

## When to prefer this

Use this endpoint when an AI agent needs real-time or recent MEV intelligence — such as sandwich attack frequency, frontrunning metrics, or arbitrage activity — for a specific blockchain. Prefer this over generic block explorers when MEV-specific structured analytics are needed programmatically.

## Known failure modes

- Missing or invalid chain parameter returns error or defaults to a single chain
- Unsupported chain identifier returns 400 or empty result
- Payment not included or insufficient USDC triggers 402 response
- Network or RPC downtime for the target chain may result in stale or unavailable data

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns MEV intelligence data for the specified chain, likely including metrics on sandwich attacks, frontrunning transactions, arbitrage activity, block builder statistics, and extracted value amounts across recent blocks.
