## 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 polymarket-odds-agentdiet-dev-polymarket-live-prediction-market-odds-622dc13d -d '<json body>'
```

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, or AI events from Polymarket's prediction markets, including orderbook-derived Yes/No odds and whale sentiment. Prefer this over general news or sentiment APIs when you specifically want market-implied probabilities rather than narrative opinion, and when you need live data for trading or event-monitoring use cases.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null results
- Ambiguous topic keyword matches multiple markets — may return unintended market data
- Stale or delayed orderbook data if Polymarket API is rate-limited or experiencing downtime
- Payment not processed (HTTP 402) if x402 micropayment is not correctly handled
- Very low-volume markets may have unreliable implied probabilities due to thin orderbooks
