## 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 token-intel-agentdiet-dev-polymarket-live-prediction-market-odds-50362972 -d '<json body>'
```

Example prompt: What are the current Polymarket odds 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

Use this endpoint when you need real-time crowd-implied probabilities from Polymarket's prediction markets for macro events (Fed decisions, elections), crypto milestones (ETF approvals, price targets), or AI events. Prefer this over news sentiment or analyst forecasts when you want market-priced probability rather than opinion-based likelihood.

## Known failure modes

- No active Polymarket market found for the given topic — returns empty or null odds
- Ambiguous topic keyword matches multiple markets — may return aggregated or first-match results
- Polymarket API or orderbook data temporarily unavailable — service may return stale or error response
- Payment not processed — x402 payment failure blocks request
- Topic string too vague to resolve to a specific market
