## 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 mcp-compiler-agentdiet-dev-polymarket-live-prediction-market-odds-f31c1d77
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities right now for Bitcoin reaching $150,000 by end of 2025? 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 from Polymarket's decentralized prediction market — particularly when you want market-implied odds (not just news sentiment) and whale/volume signals. Prefer this over general news search when you need a quantified probability rather than qualitative analysis, and over static data sources when you need live, continuously updated market prices.

## Known failure modes

- No matching market found for the given topic keyword — returns empty or null market data
- Ambiguous topic string matches multiple markets — response may include multiple markets requiring disambiguation
- Polymarket API unavailability or rate limiting — endpoint may return upstream error
- Stale or illiquid market — low volume may result in unreliable implied probabilities
- Payment failure via x402 — call blocked if USDC payment is not processed correctly
