## 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 losbeto-mev-flow-multi-chain-mev-analytics-9cc67c52
```

Example prompt: Can you pull the current MEV flow data from Losbeto for Solana — I want to see what kind of maximal extractable value activity is happening on-chain right now?

## When to prefer this

Choose this endpoint when you need MEV-specific flow data on Solana or Base chains and are operating in an x402 micropayment environment. Prefer this over general block explorers when you need structured MEV analytics rather than raw transaction data, and when your agent is already integrated with USDC micropayment rails.

## Known failure modes

- 402 Payment Required if USDC micropayment not attached
- Invalid or malformed properties parameter returns error
- Chain not supported returns empty or error response
- Rate limiting if too many calls in short window
- Upstream chain data unavailable causing stale or missing response

## How this service works

OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana and Algorand via x402.

## Output

Returns JSON containing MEV flow data for the requested blockchain(s), likely including metrics on arbitrage volumes, sandwich transactions, frontrunning activity, and value extracted per block or time window across Solana and/or Base chains.
