## 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 workflows-agentdiet-dev-polymarket-live-prediction-market-odds-a55bbc77
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities right now for 'Will the Fed cut rates in 2025'? Include volume and whale sentiment.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events directly from Polymarket's prediction market orderbooks, including volume and whale sentiment context. Prefer this over generic news or sentiment APIs when you specifically need quantified probability odds derived from actual money-backed market positions.

## Known failure modes

- Topic keyword too vague or not matching any active Polymarket market — returns empty or no results
- Polymarket API downtime or rate limiting causing stale or unavailable data
- Ambiguous topic matching multiple markets — may return aggregate or first-match results
- Payment not processed correctly via x402, resulting in 402 error before data is returned
