## 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 cve-intel-agentdiet-dev-polymarket-live-prediction-market-odds-2ea6c5df -d '<json body>'
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities for 'Will the Fed cut rates in 2025?' — and is there any whale accumulation signal?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events from Polymarket's prediction market. Prefer it over news or social sentiment APIs when you want market-implied probabilities backed by real money, and over static data sources when you need live orderbook depth and whale accumulation signals.

## Known failure modes

- Topic keyword too vague or returns no matching Polymarket market — response may be empty or return closest match
- Market not yet created on Polymarket for the queried event — returns no results
- Rate limiting or payment failure ($0.01 per call via x402) — returns 402 Payment Required
- Polymarket API downtime causes stale or unavailable data
- Ambiguous topic matching multiple markets — may return aggregated or first-match data
