## 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-88c19465
```

## When to prefer this

Choose this endpoint when you need live, crowd-sourced implied probabilities from Polymarket's real-money prediction markets for macro, crypto, political, or AI events — especially when you want orderbook depth, volume context, and whale sentiment rather than simple news or analyst forecasts. Prefer this over general news APIs or sentiment tools when the user wants quantified market-implied odds backed by real capital at risk.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null market data
- Ambiguous topic matches multiple markets — may return the most popular match or a list
- Polymarket API unavailable or rate-limited — upstream fetch failure
- Stale orderbook if Polymarket data stream is lagging — probabilities may not reflect the last trade
- Payment not processed (HTTP 402) — call blocked if x402 micropayment not included
