## 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 shopify-intel-agentdiet-dev-polymarket-live-prediction-market-odds-d4d5656c
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities for 'Will the Fed cut rates in 2025?' — pull the current orderbook and whale sentiment too.

## When to prefer this

Use this endpoint when an agent needs real-time crowd-sourced probability estimates from Polymarket for macro, crypto, political, or AI events — especially when you want orderbook depth and whale sentiment alongside implied odds. Prefer this over news sentiment APIs when you want market-backed probability, not editorial opinion. Best for financial agents, research tools, and any workflow where prediction market consensus is a signal.
