## 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 oyapicks-arbitrage-cross-venue-prediction-market-price-gaps-b1580048
```

Example prompt: Are there any prediction markets right now where the same outcome is priced differently on Polymarket versus Alpha Arcade? Show me the biggest cross-venue price gaps I could potentially arbitrage.

## When to prefer this

Use this endpoint when you specifically want to compare the same prediction market outcome across Polymarket and Alpha Arcade to find cross-venue pricing discrepancies. It is distinct from the OyaPicks volume spikes or movers endpoints — those track momentum on a single venue, while this endpoint is purpose-built for cross-platform arbitrage detection.

## Known failure modes

- No arbitrage gaps found at query time — markets may be efficiently priced across venues in that moment
- Stale data if market prices have moved since last fetch
- One or both venues may be temporarily unreachable, causing incomplete comparison
- Rate limiting or payment failure for the $0.05 USDC x402 charge
