## 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 emc2ai-io-bd8cdf19 -d '<json body>'
```

Example prompt: Find me current cross-chain arbitrage opportunities for ETH/USDC between Ethereum, BSC, and Base — show the price discrepancies and which DEX routes are most profitable right now.

## When to prefer this

Use this endpoint when you need real-time cross-chain arbitrage intelligence powered by Bitquery's blockchain indexing. It is best suited for DeFi agents or trading bots that need to identify price inefficiencies across multiple chains and DEX protocols simultaneously, rather than querying individual DEX APIs one at a time.

## Known failure modes

- Insufficient liquidity data for a requested token pair returning empty results
- Chain not supported returning an error
- Stale price data if on-chain indexing lags behind real-time markets
- Payment failure if USDC balance is insufficient for the $1 per call fee
- Rate limiting if called too frequently

## How this service works

Cross-chain price discrepancies and profitable arbitrage routes.

## Output

Returns a list of cross-chain arbitrage routes including the token pairs involved, the DEX protocols on each chain with their respective prices, the spread percentage, and estimated profit potential for each route.
