## 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-0430f7b3 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, political, or AI events, especially when you want whale trading sentiment and volume data alongside implied probabilities. Prefer this over news APIs when you want market-derived probability rather than editorial opinion, and over general data APIs when Polymarket-specific orderbook depth and whale activity are required.

## Known failure modes

- Topic keyword matches no active Polymarket markets — returns empty or null results
- Ambiguous topic keyword returns multiple unrelated markets requiring disambiguation
- Polymarket API downtime or rate limiting causes failed fetch
- Stale orderbook data if underlying Polymarket feed lags
- Payment failure via x402 prevents API access
