## 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-9c5c136c
```

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities for 'Will the Fed cut rates in 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, or AI events sourced specifically from Polymarket's prediction market orderbooks. It is ideal for agents that need market-implied probabilities rather than model-generated forecasts, or when whale sentiment and actual trading volume are required to gauge conviction. Prefer this over general news or sentiment APIs when quantitative probability data is needed for decision-making or display.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Stale or unavailable Polymarket data if upstream API is down — may return cached or error response
- Ambiguous topic keyword matching multiple markets — may return the most liquid or first-matching market
- Payment failure via x402 if USDC balance is insufficient — returns 402 Payment Required
- Rate limiting or quota exhaustion — returns 429 Too Many Requests
