## 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 llms-generator-agentdiet-dev-polymarket-live-prediction-market-odds-063abc1d -d '<json body>'
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities for Bitcoin reaching $150k this year — and is there any notable whale activity or volume I should know about?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for binary events (macro, crypto, AI, political) rather than analyst forecasts or news sentiment. It is specifically grounded in Polymarket's decentralized orderbook, making it ideal for agents that need market-implied probabilities with volume and whale positioning context rather than simple news or price data.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Polymarket API unavailable or rate-limited — upstream fetch failure
- Ambiguous topic string matches multiple unrelated markets — may return unexpected results
- Very new or niche markets may have thin orderbooks and unreliable implied probabilities
- Payment failure via x402 if USDC balance is insufficient
