## 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 blockrun-ai-1dffc833
```

Example prompt: What are all the open and historical Polymarket positions for wallet address 0x1234abcd...? I want to see every prediction market they've held shares in.

## When to prefer this

Use this endpoint when you need to look up a specific wallet's Polymarket positions — both currently open and historical — especially within an agent workflow analyzing prediction market portfolios, tracking trader behavior, or auditing on-chain prediction market activity. Prefer this over generic blockchain explorers when you specifically need structured Polymarket position data.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet address with no Polymarket activity may return empty positions array
- Network timeout or upstream Polymarket data unavailability
- Rate limiting if too many requests are made in quick succession
- Payment failure if x402 USDC payment is not correctly handled
