## 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 sec-intel-agentdiet-dev-polymarket-live-prediction-market-odds-10cc4b58 -d '<json body>'
```

Example prompt: What are the live Polymarket odds right now for the Fed cutting rates at the next FOMC meeting — give me the implied Yes/No probabilities and any notable whale sentiment?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as reflected by actual money-on-the-line prediction market participants on Polymarket. Prefer this over news sentiment tools when you want quantified probability estimates backed by real trading volume and whale positioning rather than qualitative sentiment. Best for FOMC rate decisions, crypto price milestones, election outcomes, and major geopolitical events.

## Known failure modes

- No matching Polymarket market found for the queried topic — returns empty or null market data
- Topic too vague to resolve to a specific market — may return multiple candidates or an error
- Polymarket API or orderbook data temporarily unavailable — upstream timeout or 5xx error
- Payment not processed correctly — x402 payment required error before data is returned
- Rate limit exceeded — too many requests in a short window
