## 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-3e1e3029
```

Example prompt: What are the live Polymarket odds and implied probability right now for 'US recession in 2025' — include whale sentiment and trading volume if available?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events, particularly when you want market-implied odds (not just news sentiment) and whale positioning signals. Prefer this over news APIs or social sentiment tools when you need a quantified probability backed by real money at stake on Polymarket.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic matches multiple markets — may return the most relevant or a list
- Polymarket API or data feed is temporarily unavailable — upstream timeout or error
- Payment not processed (HTTP 402) — x402 micropayment must succeed before data is returned
- Very low-volume or newly created markets may have sparse orderbook data
