## 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 agentrxi-polymarket-prediction-odds-4c160764
```

Example prompt: What are the current Polymarket odds on a Fed rate cut happening this year? Show me the top 10 markets on that topic with their implied probabilities and volumes.

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates on future events — elections, economic decisions, crypto prices, geopolitical events, or sports outcomes. It is ideal over traditional news or analysis APIs when you want a market-implied probability rather than a qualitative opinion. Prefer it over scraping Polymarket directly because it returns structured, parsed data including volume and liquidity signals that help assess market depth and reliability.

## Known failure modes

- Empty result set if query term matches no active Polymarket markets
- Rate limiting or payment failure if USDC balance is insufficient for the $0.006/call fee
- Stale or delayed odds if Polymarket data feed is temporarily lagged
- Invalid limit parameter (outside 1–50 range) causing a validation error
- Network timeout if Polymarket upstream is slow or unreachable
