## 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 x402-audit-agentdiet-dev-polymarket-live-prediction-market-odds-ec9c5979 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's live orderbooks — especially when you want implied probability percentages, volume context, and whale positioning rather than news sentiment or analyst forecasts. Prefer this over general web search when you specifically want quantified market-derived probabilities.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or low-confidence results
- Polymarket API unavailable or rate-limited — upstream fetch failure
- Ambiguous topic keyword matches multiple markets — may return multiple or incorrect markets
- Payment failure via x402 — 402 response if USDC payment not completed
- Stale data if Polymarket orderbook has low liquidity or market is recently resolved
