## 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 serp-extract-agentdiet-dev-polymarket-live-prediction-market-odds-5e6c033c -d '<json body>'
```

Example prompt: What are the current live Polymarket odds and implied Yes/No probabilities for 'Will the Fed cut rates in Q3 2025?' — including volume and any whale sentiment signals?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for specific events — especially macro, crypto, or AI/political outcomes — and want not just odds but also volume and whale sentiment context. Prefer this over general news search when you need a quantified probability signal rather than qualitative commentary, and over on-chain DEX tools when the question is about event outcomes rather than token prices.

## Known failure modes

- Topic too vague or ambiguous — no matching Polymarket market found, returns empty or error response
- Polymarket API or orderbook data temporarily unavailable — upstream failure
- Rate limiting or payment failure (HTTP 402) if x402 USDC payment is not properly attached
- Topic string too short (violates minLength:1) — validation error
- Market for queried event has closed or expired — stale or no data returned
