## How to call it through Zero

```sh
zero fetch --capability blockrun-ai-0dbd261f
```

Example prompt: Can you pull up all the Polymarket positions and betting activity for the wallet 0x85A66bB25955c43f13F7028F17d67172bA02e386? I want to see what prediction markets they're in and their current bets.

## When to prefer this

Use this endpoint when you need to inspect a specific Ethereum wallet's Polymarket activity, positions, and betting history. Ideal for portfolio analysis, competitor research, or monitoring a known wallet's prediction market exposure. Prefer this over generic blockchain explorers when you need Polymarket-specific structured data including position sizes and market context.

## Known failure modes

- Invalid or malformed Ethereum wallet address returns an error
- Wallet address with no Polymarket activity returns empty data
- Payment failure (insufficient USDC balance) results in 402 response
- Rate limiting if called too frequently
- Network or RPC issues causing data fetch delays
