## 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 workflows-agentdiet-dev-polymarket-live-prediction-market-odds-d24a597a

## When to prefer this

Choose this endpoint when you need real-time, crowd-sourced probability estimates for macro, political, crypto, or AI events sourced directly from Polymarket's live orderbooks. It is superior to news sentiment or analyst forecasts when you want market-implied probabilities with volume and whale positioning. Prefer this over generic news APIs when you need quantified probability signals rather than qualitative coverage.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null market data
- Ambiguous topic string matches multiple markets — may return multiple or unexpected markets
- Polymarket API downtime or rate limiting causing stale or missing data
- Topic too broad results in irrelevant market matches
- Payment failure via x402 causes 402 response with no data returned
