## 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 whale-momentum-agentdiet-dev-polymarket-live-prediction-market-odds-dc66e72b

Example prompt: What are the live Polymarket odds and whale sentiment right now on whether the Federal Reserve will cut interest rates at the next FOMC meeting?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for future events — especially macro, crypto, political, or AI milestones — derived from actual money-on-the-line prediction market orderbooks rather than sentiment surveys or news analysis. It is particularly useful when whale trading activity and volume context matter alongside raw odds.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Ambiguous topic matches multiple markets — may return results for the wrong event
- Stale data if Polymarket API or orderbook feed is temporarily unavailable
- Payment failure via x402 if USDC balance is insufficient (HTTP 402)
- Rate limiting or timeout if the upstream Polymarket data source is slow
