## 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 github-audit-agentdiet-dev-polymarket-live-prediction-market-odds-8db50291
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities right now for 'Bitcoin ETF approval' — include volume and whale sentiment if available?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's live orderbooks. It is ideal when you want implied market probabilities rather than news sentiment or analyst forecasts, and when whale trading behavior is relevant to your analysis.

## Known failure modes

- Topic keyword returns no matching Polymarket market — empty or null result
- Polymarket API or orderbook data temporarily unavailable — service timeout
- Ambiguous topic keyword matches multiple markets — may return aggregated or first-match result
- Payment authorization failure via x402 — 402 response before data is returned
- Stale orderbook data if market liquidity is very low
