## 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-ee40b861 -d '<json body>'
```

Example prompt: What are the current Polymarket odds and implied Yes/No probabilities for the US entering a recession in 2025, including volume and whale sentiment?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events from Polymarket's live orderbooks. It is ideal when you want implied market probabilities backed by actual money (not just sentiment polls), and when whale positioning or volume signals matter for decision-making. Prefer this over news sentiment endpoints when you need a single calibrated probability number for an event outcome.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null market data
- Polymarket API unavailable or rate-limited — upstream timeout or error response
- Ambiguous topic keyword matching multiple markets — may return the most relevant or require refinement
- Market has expired or settled — returns historical final probabilities rather than live odds
- Payment authorization failure via x402 — request blocked before execution
