## 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 json-repair-agentdiet-dev-polymarket-live-prediction-market-odds-97b9e5b0
```

Example prompt: What are the live Polymarket odds and implied Yes/No probability for Bitcoin hitting $150k by end of year? I want to see the current volume and whale sentiment too.

## When to prefer this

Choose this endpoint when you need real-time, crowd-sourced implied probabilities for macro, crypto, geopolitical, or AI events directly from Polymarket's live orderbooks. It is especially valuable when you want market-derived probability estimates (rather than analyst forecasts) and need whale sentiment or volume context alongside the odds. Prefer this over general news or sentiment endpoints when quantified prediction market data is the goal.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Polymarket API or data feed temporarily unavailable — upstream connectivity error
- Ambiguous topic matches multiple markets — may return best-guess or require more specific query
- Payment not processed (x402) — endpoint returns 402 if micropayment fails
- Rate limiting or quota exceeded — returns error if too many calls in short window
