## 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-65e39a0d -d '<json body>'
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities right now for 'Will the Fed cut rates in 2025'? I want the current orderbook sentiment and whale activity too.

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events and want market-implied odds rather than analyst forecasts. It is ideal for agents performing risk assessment, trading signal generation, or event-driven decision making that benefits from decentralized prediction market data and whale sentiment. Prefer this over news APIs when you need quantified probability rather than qualitative coverage.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Stale or unavailable orderbook data if Polymarket API is temporarily down or rate-limited
- Ambiguous topic string matching multiple unrelated markets, returning mixed or averaged data
- Payment failure via x402 protocol resulting in 402 response and no data returned
- Malformed or too-short topic string triggering schema validation error
