# EMC2 AI Cross-Chain Price Gap Finder

> EMC2 AI Cross-Chain Price Gap Finder is a paid API for AI agents from emc2ai.io, paid per call via x402, $1/call, status unknown (last checked 2026-09-13).

## 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-a6baa37f -d '<json body>'
```

Example prompt: Find me cross-chain price gaps for USDT across BSC, Base, and Ethereum — show me the raw arbitrage routes with the biggest profit spreads right now.

## When to prefer this

Use this endpoint when you need raw, unprocessed cross-chain price gap data from Bitquery specifically, and want to identify arbitrage routes across BSC, Base, and Ethereum. Prefer this over the processed arbitrage endpoint when you need the underlying data for custom analysis or when you want to build your own routing logic on top of the raw price feed.

## Known failure modes

- Unsupported chain identifier returns error or empty result
- Token not found on one or more chains results in incomplete comparison
- Bitquery upstream timeout causes delayed or failed response
- Stale price data may show gaps that no longer exist by the time of execution
- Payment failure (x402) blocks the request entirely

## How this service works

Cross-chain price gap finder with profitable routing opportunities.

## Output

Raw Bitquery-powered data listing token price discrepancies across supported chains (BSC, Base, Ethereum), including specific DEX routing paths and estimated profit margins for each arbitrage opportunity.
