# CoinOpSelect MEV Analyze

> CoinOpSelect MEV Analyze is a paid API for AI agents from coinop.publicvm.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Analyzes a blockchain transaction for MEV (Maximal Extractable Value) opportunities, returning detected arbitrage, sandwich, or other MEV patterns.

## 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 coinopselect-mev-analyze-285c75a8 -d '<json body>'
```

Example prompt: Can you analyze this transaction for MEV opportunities? The tx goes to 0x1111...1111 with hash 0xabc123, input data 0x, value 0.2 ETH, and gas price 20 gwei.

## When to prefer this

Choose this endpoint when you need to programmatically detect MEV exposure, frontrunning risk, or arbitrage opportunities within a specific on-chain transaction, especially on Base or EVM-compatible chains. Prefer it over generic blockchain explorers when you need structured MEV-specific intelligence rather than raw transaction data.

## Known failure modes

- Missing or malformed tx object returns an error or empty opportunities array
- Invalid transaction hash format may result in analysis failure
- Network timeouts if the blockchain node is unreachable
- Payment failure via x402 if USDC balance is insufficient (HTTP 402)
- Transactions with missing fields (e.g. no gasPrice) may yield incomplete analysis

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object with a 'query' field set to 'mev-analyze' and an 'opportunities' array listing any detected MEV patterns, arbitrage vectors, or sandwich attack signals found in the analyzed transaction. An empty array indicates no MEV opportunities were detected.
